It’s quite normal. I had them with my first and currently at 26 wks with my second and having them as well when I lie on my side. As long as you feel kicks and movements from your baby, then there’s no concern. This is just your baby growing. If the pains do wake you up at night and keep you awake the whole night meaning it’s almost unbearable, always best to see your doctor to ease your worries.
If not, try pregnancy pillow or have a pillow below your tummy when you lie on your side
Hope this helps :)
