Or if your farther along like me (37&2) then it could be your pelvic bone spreading apart to give baby more room to come through when the time comes but its completely normal. still talk to your doc/midwife about it
Another reason for those pains might be if ur constipated....same happened to me because i was constipated and the doctor gave me some pills...and another good thing to drink its lots of water and prune juice....
Don't worry. What you are experiencing are typical pregnancy pains. You should talk to your doctor about it but from my own experience I would say it's nothing serious. I'm 19wks pregnant and I've experienced pressure and pain due to ligament stretching. The lining protecting your uterus stretches as your baby grows and your uterus expands. Your organs will shift a little too. Only some women don't feel a thing when all this happens in their bodies! I hope you'll feel better soon. Just be patient and take it easy. Wishing you all the best.
