13th week of pregnancy
Good news for your 13th week of pregnancy: With the start of the second trimester, you may start to feel more energized and well. The first pregnancy fatigue and nausea will gradually start to subside, so you are approaching the “honeymoon” period of pregnancy; it is possible that you will feel more energetic in the coming weeks!
This week, you may have an appointment for a 13-week ultrasound or genetic testing (NIPT). This test screens for chromosomal abnormalities. The sex of your baby may be known this week – but you may need to wait a little longer to know for sure.
The end of the 13th week also means the end of the first trimester! You are now a third of the way through your pregnancy. At 13 weeks pregnant, you are still growing a miracle baby with vocal cords, teeth and even fingerprints – how wonderful! If you’ve kept this incredible news largely secret, it might be time to share it with joy.
Development of the Baby in the 13th Week of Pregnancy
Your miracle baby is growing fast as we approach the second trimester! At 13 weeks, your baby starts to urinate and this urine mixes with the amniotic fluid. Don’t worry, swallowing amniotic fluid is completely safe and a natural part of the development process. Your baby may even start sucking your thumb!
Will she be a talker or a singer with a beautiful voice? It is not yet known, but the vocal cords start to develop this week. These vocal cords will make their first appearance on the baby’s birthday with the first scream!
13 Week Baby Sizes
Your baby is the size of a lemon this week! It is about 7.3 cm long and weighs 23 grams. Proportionally, his head is now about 1/3 of his body (it was half the size in previous weeks).
How many months is a 13-week pregnancy?
At 13 weeks pregnant, you are almost three months pregnant. This is the last week of the first trimester! (We won’t get tired of saying this because getting here is a great milestone!)
13th Week of Pregnancy Ultrasound
An ultrasound at this week may reveal the sex of the baby, but your doctor will probably wait for a mid-pregnancy ultrasound (between 18-22 weeks) as it can be a bit difficult to see the details that indicate whether it will be a boy or a girl.
If you have opted for an extracellular DNA test, a genetic test (NIPT), you will be screened for chromosomal abnormalities and the results will tell you the sex of your baby.
13th Week of Pregnancy Pregnancy Symptoms
At 13 weeks you may notice some changes in your pregnancy symptoms. You may be able to get through the day without nausea or the need to sleep all the time. However, you may still experience some of these symptoms:
Visible Veins: You may notice blue lines and spider veins under your skin due to increased blood flow.
Increased Energy The second trimester is known for feeling energized and having the fewest symptoms. As you start to feel better and more energized, you may feel the urge to tackle your to-do list. If you have been feeling too tired or sick to exercise until this time, now is a good time to get back into an exercise routine. Exercise can even make labor easier – it’s definitely worth it!
Increased sexual desire: If you are feeling eager to have sex, enjoy it! When you are 13 weeks pregnant, you may have some light bleeding after intercourse; this is due to the cervix being more sensitive and is normal. However, if you have heavy bleeding like menstruation, you should call your doctor. Otherwise, you can spend time alone with your partner during this period and make use of this increased sexual desire.
For expectant mothers of twins: If you are expecting twins, nausea and fatigue may persist. This is because there is more hCG hormone in your body. Be sure to tell your doctor if the nausea and vomiting are very severe. If you can eat solid and liquid foods but still feel nauseous, hang in there; these symptoms may soon ease.
What Does the 13th Week of Pregnancy Look Like?
By week 13, after the morning sickness, fatigue and other challenges of the first trimester, you may feel like you’ve turned the corner. You may feel some indigestion, aches and pains or fatigue, but you will feel much more comfortable in the second trimester.
13 Weeks of Pregnancy
Your uterus has now grown enough to expand to the top of your pelvis, which means you now look pregnant. From now on, your belly will start to become more prominent, because it is recommended that you gain weight slowly when you are carrying a 13-week-old fetus.
The recommended weight gain during pregnancy is as follows:
BMI stands for body mass index. If you don’t know your BMI, you can calculate it here.
- If you are underweight (BMI below 18.5):
Recommended total weight gain: 12.5-18 kg
In the second and third trimester: Aim to gain 0.5-0.6 kg per week. - If you are of normal weight (BMI 18.5-24.9):
Recommended total weight gain: 11.5-16 kg
In the second and third trimester: Aim to gain about 0.4-0.5 kg per week. - If you are overweight (BMI 25-29.9):
Recommended total weight gain: 7-11.5 kg
In the second and third trimester: Aim to gain about 0.3-0.4 kg per week. - If you are obese (BMI 30 and above):
Recommended total weight gain: 5-9 kg
In the second and third trimester: Aim to gain about 0.2-0.3 kg per week. - If you are expecting twins:
Recommended total weight gain: 17-25 kg
Aim to gain about 0.5 kg per week in the first half of pregnancy and a little more per week in the second half.
How much caloric needs increase during pregnancy is controversial, as data show that it varies widely between women (although it is usually an extra 300 to 500 calories). One researcher suggests replacing the phrase ‘meal for two’ with ‘meal for 1.1’ to better reflect the moderate increase in daily calories. Focus on nutrient-dense foods so that every bite is as packed with nutrients as possible.
Of course, don’t worry too much about these numbers; the important thing is to eat a healthy, nutritious diet, support your body with about 300 extra calories a day compared to pre-pregnancy, and get enough exercise.
At 13 Weeks, How Do You Feel Your Belly?
You are probably feeling better now about nausea and morning sickness. However, your uterus may be expanding upwards and outwards to make room for your rapidly growing fetus. This expansion can make the skin of your abdomen feel itchy and stretched, so make sure you keep it moisturized and eat a healthy diet to keep it soft.
Can You Feel Your Baby at 13 Weeks?
Probably! It’s different for everyone, but some women (especially those who have been pregnant before) can start to feel baby movements at 13 weeks. Don’t worry if you haven’t felt the first movements yet; you have until week 25 to feel these so-called “quickening” movements!
Tips for the 13th week of pregnancy
Recognize the Symptoms of Urinary Tract Infection (UTI): If left untreated, a UTI can spread to the kidneys and put both you and your baby’s health at risk. Consult your doctor if you feel the need to use the toilet more often, have a burning sensation when urinating, or if urine looks or smells abnormal. Your doctor can test for bacteria and prescribe antibiotics if necessary.
Strengthen your pelvic floor: In the 13th week of pregnancy, your body needs all the support it can get. The pelvic floor can be weakened by pregnancy and previous birth(s), but Kegel exercises are a great way to strengthen this area. These exercises don’t require a lot of time or effort; practicing a regular routine throughout pregnancy can reduce the risk of postpartum urinary incontinence and increase sexual instinct.
Spend Time Together: There may be a spark between you and your partner, but don’t forget to have fun together outside the bedroom. Strengthen your bonds by spending quality time together before the baby arrives.
Start your day with a healthy breakfast: No more morning sickness? Time for breakfast! This is the perfect opportunity to get calcium, protein and powerful nutrients from whole grains and vegetables. A healthy morning meal can help you maintain a balanced diet throughout the day.
These small but effective steps will support you to have a healthier and more enjoyable 13th week!
Frequently Asked Questions About the 13th Week of Pregnancy
How Long Does the Second Trimester Last?
At 13 weeks you have not yet completed the first trimester, but next week you will enter the second trimester. The second trimester starts at week 14 and lasts until week 27 (26 weeks and 6 days to be precise), which is 13 weeks in total. This period, which marks the middle of the pregnancy, is usually characterized by a period of mild symptoms and increased energy.
How Can I Cope with 13 Weeks of Persistent Morning Sickness?
In most cases, morning sickness subsides by 13 weeks, but for some pregnant women it can last until 16 weeks (or longer). If you experience nausea during this period, you can try to alleviate it by eating small snacks throughout the day, choosing light, stomach-friendly foods (for example, pretzels or oats), getting plenty of protein and drinking plenty of water.
If symptoms are severe, you should talk to your doctor to rule out the possibility of another illness or hyperemesis gravidarum (extreme nausea and vomiting). You can also discuss with your doctor the possibility of adding ginger and vitamin B6 to your diet, or medication options if necessary.
How Can I Prevent Varicose Veins During Pregnancy?
The risk of varicose veins increases during pregnancy due to increased blood flow. To prevent varicose veins, you should avoid tight or tight-fitting clothes, elevate your feet when sitting and avoid standing or sitting still for long periods of time. Remember that varicose veins can be genetic, so if they run in your family, it can be difficult to prevent them completely. However, these steps can help you minimize your risk of varicose veins.
When Can I Start Yoga During Pregnancy?
Prenatal yoga is a great option for physical activity during pregnancy. It’s generally safe to do at any stage of pregnancy, but every pregnancy is different, so it’s important to check with your doctor before you start. It’s also helpful to talk to your yoga instructor before class to let them know about any adjustments you may need, so that you can participate in the practice comfortably and safely.
Is it Normal to Have New Moles During Pregnancy?
Along with your growing belly, you may also experience changes in your skin during pregnancy due to the effects of hormones. In particular, you may notice dark spots on your face, such as melasma, known as the “pregnancy mask”, which can become more noticeable when exposed to the sun. Also, the color or shape of existing moles may change. This is usually normal, but it is still best to talk to your doctor or a dermatologist if you notice any changes.
