Your Body at 15 Weeks Pregnant
At 15 weeks pregnant, you may feel the occasional stabbing pain at the sides of your bump. This kind of stomach pain is usually what's known as ‘round ligament pain’ and is caused by your ligaments stretching to make room for your growing foetus. Putting your feet up and resting can help with this. Stomach cramps and pains aren't usually anything serious as long as they are mild and don't last long, but do speak to your midwife or doctor if you're worried. You may also experience back pain during pregnancy. This might be caused by hormonal changes that affect the ligaments in your body, putting strain on your lower back. Here are some things you can do to avoid or ease back pain:

What Size Is a Pregnant Belly at 15 Weeks?
At 15 weeks pregnant your baby bump may be starting to show or getting more prominent, so you may notice people sneaking curious glances at your tummy. Keep in mind that it’s OK if you haven’t noticed much of a bump yet. Some pregnant people don’t show for another week or two – every pregnancy is unique.
Whether you notice your baby bump yet or not, you may be curious to know if you can feel your baby move at 15 weeks pregnant. Even though your little one may be moving around right now, it’s unlikely that you’ll feel those tiny movements yet, especially if this is your first pregnancy. However, most movements are felt for the first time between 16 and 24 weeks – so keep an eye out for tiny flutters in the next few weeks.
