15 Weeks Pregnant: Your Symptoms

At 15 weeks pregnant, here are some of the symptoms you may be experiencing:

• Swollen feet and legs. One condition that may crop up is edema, a type of swelling that may occur in your feet, lower legs or even in your hands and arms, with swollen feet and ankles being among the most common symptoms. Edema occurs when your body retains fluid, which can happen during pregnancy. Swollen feet may also be caused by the hormone relaxin, which causes the ligaments in the feet to loosen and the bones to spread. To help reduce some of the swelling, you could try soaking your feet in a cool foot bath and elevating them whenever possible.

• Swollen, bleeding gums. Red, swollen gums that feel sensitive and tend to bleed when you brush and floss may be caused by pregnancy hormones that increase the likelihood of inflammation and gum disease, such as gingivitis. Such gum diseases have been linked to an increased risk of preterm birth. The good news is you can help alleviate any discomfort and irritation by rinsing with salt water and brushing with a soft-bristled toothbrush. You could also contact your dentist for expert advice on what to do. Just don’t abandon your regular dental care routine of brushing and flossing daily and visiting your dentist every six months.

• Nasal congestion. If you feel as if your nose is constantly stuffy or if you suffer from nosebleeds, you might be able to blame these symptoms on pregnancy hormones. Whether it's at 15 weeks or throughout your pregnancy, those pesky hormones may cause the mucous membranes in your nose to swell and dry out. Make sure you stay hydrated and try saline nasal drops for relief.

• Lower back pain. If you’re feeling lower back pain at 15 weeks pregnant, you’re not alone—many pregnancies experience this symptom. Practicing good posture can help, and so can wearing low-heeled shoes with good support. And at 15 weeks, moderate exercise that strengthens your back muscles can also help prevent or alleviate lower back pain, swelling and cramps during pregnancy.

• Weight gain. With any luck, morning sickness is behind you now. Your appetite may have returned, and you may start noticing some weight gain at 15 weeks pregnant. Your little one is growing, and at 15 weeks pregnant your belly may start to appear more prominent.

• “Pregnancy brain.” Feeling more forgetful lately? This could be thanks to hormonal changes, lack of sleep or even stress. Experts don’t yet know whether pregnancy has a real impact on your memory and mental sharpness, but if you feel more scatterbrained than usual, just know that many others feel the same way. Try using your tablet or smartphone to stay organized with lists and reminders.

• Spider veins. As pregnancy leads to changes in your circulation and increased blood volume, you may start to notice thin, red veins under the skin of your face or legs. Regular exercise and elevating your feet whenever possible can help improve your circulation and reduce your chances of getting spider veins, which may fade after you give birth.

• Urinary tract infections. Pregnancy can make you more prone to UTIs. If you have pain when you pee, a strong urge to pee immediately, a fever or back pain, inform your healthcare provider. Your provider may prescribe antibiotics to help prevent a more serious bladder or kidney infection.

How Big Is a Pregnant Belly at 15 Weeks?

As mentioned above, every pregnant belly develops at its own rate, and you may or may not be showing right now. It’s possible that your pregnant belly’s size will become more evident at around 15 weeks, as a baby bump usually starts to show around weeks 12 to 16. During your second trimester, your uterus is positioned higher and more forward and is growing out of your pelvis as it becomes bigger.

Whether you're showing or not, you may be curious to know if you can feel your baby move at 15 weeks. Your little one is becoming more active and is moving around inside your uterus; however, you may or may not have felt those movements yet at 15 weeks pregnant. It's likely that by around 18 to 20 weeks you'll feel your baby move for the very first time, which is known as quickening.

15 Weeks Pregnant: Things to Consider

We’re here to help you on your journey through pregnancy. Check out our handy list of important things to think about at 15 weeks pregnant:

• The best way to keep your energy levels up and help tone your muscles is through mild exercise like walking, swimming or yoga. Just make sure your healthcare provider gives you the OK before starting a new exercise routine. Walking is a great choice because it’s low-impact, and you can motivate yourself by walking with a friend or family member as a nice outing. Consider using an app or another kind of tracking device that can show you how active you are on a daily basis. Download our guide to pregnancy exercise for more must-have information.

• Have you given any thought to where you’ll give birth? Experts consider hospitals and accredited birth centres to be the safest, and you can learn more about your options from your healthcare provider. Once you’ve settled on where, you might be able to arrange a tour of the hospital or centre before you give birth. You can also use the second trimester to find out what other labour and delivery choices are available to you. For example, what comfort measures can you take advantage of, and who can be with you during labour and delivery.

• Before long, your little one will be able to hear sounds, and it might be fun to spend a time every day listening to your favorite music together. Listening to music is also one of the many ways to relax and lower your stress levels during pregnancy.

• For most people, sex can be perfectly safe during pregnancy. Keep the lines of communication open with your partner and speak to your healthcare provider if you have questions about sex during pregnancy. Keep in mind that it’s natural for your or your partner’s sex drive to be different, and it can even ebb and flow as you move through pregnancy. For you in particular, it can be influenced by things like pregnancy hormones, your growing belly, your feelings about all the changes taking place and any symptoms you may be experiencing at 15 weeks pregnant and throughout your pregnancy.

• If you hope to find out your baby’s gender at the mid-pregnancy ultrasound, it’s not too far off. This ultrasound is usually done somewhere between 16 and 20 weeks of pregnancy, so at 15 weeks, you’re almost there. In the meantime, take our fun What’s Your Baby’s Gender quiz.
