15 Weeks Pregnancy Symptoms

Pregnancy symptoms at week 15 might be non-existent for a lot of women. The second trimester marks the end of morning sickness and a lot of other energy-sapping signs of pregnancy for many mothers, but others still experience symptoms at this stage. Here are the most common signs of pregnancy at week 15:

  • Increased sex drive
    For many women, a common sign of pregnancy at 15 weeks is an increase in their libido. This is down to the hormonal changes in your body – estrogen levels play a big part in your moods and sex drive. Libido will fluctuate throughout your pregnancy and there will be days where you couldn’t think of anything worse than sex, too.
  • Increased appetite
    It’s normal, and recommended, to put on weight during pregnancy. At 15 weeks pregnant, your body will need an ever-increasing supply of sustenance to support the healthy growth of your incoming baby. If you have any healthy food cravings, indulge in them to make sure you are intaking a good level of vital nutrients and vitamins – it’s important to pay attention to your diet when you are pregnant.
  • Headaches

A common pregnancy symptom at week 15 is headaches. These can be a result of extreme tiredness, stress, hormonal changes, and many other pregnancy-related changes.

  • Confusion

It has been shown that cognitive function during pregnancy declines slightly due to the possible influence of increased levels of pregnancy hormones. So, if you have experienced any slight lapses in concentration and/or memory loss, don’t worry, it’s one of the more common signs of pregnancy at 15 weeks.

  • Nosebleeds

The increase in blood flow around your body during pregnancy can lead to the occasional nosebleed. This is a fairly common sign of pregnancy, but if the problem persists or worsens, you should consult your medical practitioner for advice.

Your Body at Week 15

You may have noticed an increase in varicose veins appearing on your breasts, legs, and abdomen. This is your body adapting to the presence of your baby, as it increases the vein network to support the transportation of vital nutrients to your baby.

The second trimester also marks a period of time where you are likely to put on a lot of weight. Investing in some loose, breezy clothes will be a good idea so that you have some extra room to feel comfortable throughout the rest of the pregnancy. When you are 15 weeks pregnant, the baby bump will become more pronounced, and other people might start noticing that you are expecting.

Your body is changing in other ways, too, and you may start to notice that you have swollen gums. Pregnancy hormones can trigger inflammation of the gums. If you notice a small bump on your gums, this could be a pregnancy tumor, which are mostly harmless and tend to go away by themselves after a short period of time.

Baby Size at Week 15

Your baby gained a lot of weight during the last week and will now weight around 70 grams. The fetus at 15 weeks will now be around the same size as an apple.

From what was once a tiny little seed-sized embryo, at 15 weeks the fetal development progress is quite astonishing. All of your baby’s vital organs will have formed and are becoming stronger every day. Muscles and bones are strengthening and becoming harder, and the head will now be looking more proportional in size to the rest of the body. Although rare, some mothers have even reported being able to feel their baby move inside them at 15 weeks pregnant.

Another important development is that your baby has begun to practice breathing for preparation when outside the womb. They are drawing in fluid through the nose into upper respiratory tract, developing the lungs in the process. At this stage, the skin is translucent and covered in lanugo (fine hairs).

Week 15 Pregnant Ultrasound

It’s not common to have an ultrasound at week 15 of pregnancy. The first scan is usually performed between weeks 8 and 14, and the second scan is usually carried out between weeks 18 and 21. Exceptions to this rule are high-risk pregnancies – if you are vulnerable to any abnormalities or discrepancies, your medical may schedule an ultrasound for this week.


Your stomach will feel tight and very firm when you are 15 weeks pregnant. This is because the womb is expanding beyond the pelvic region and you may even be able to feel the fundus – which is the broad and curved upper region of the uterus.

You should expect some relief from the early pregnancy symptoms at week 15. Most women notice their pregnancy symptoms subside after the first trimester.

This stage of pregnancy is often referred to as the “honeymoon phase”. The reason for this is that many women feel much more energised and don’t experience any of the early signs of pregnancy that were prevalent during the first weeks.

You will look noticeably more pregnant at week 15, as the uterus is too big to fit inside the pelvis. This means that your baby bump will become more pronounced.

Tips for Week 15 of Pregnancy

  • Purchase a planner
    If “pregnancy brain” has began to affect your ability to function in everyday tasks, it might be a good idea to purchase a diary or planner to help you remember important things and keep you organised.
  • Eat regularly

Eating consistently is important to fuel the healthy development of your body and help your body cope with the changes it is experiencing. If you are forgetting to eat, try setting an alarm every few hours to remind yourself.

  • Get plenty of rest
    Just as food is important to nourish the baby’s development, so is sleep. You should listen to your body and sleep when you are tired, your energy levels may be sapped due to your system working overtime on maintaining a healthy pregnancy.
