Could be Braxton hicks. I describe mine as tightening down in the pelvic area but it could feel like pressure. But just like one other lady said ^ lay down and drink lots of water.
I had the same issues, the doctor said my ligaments are stretching plus I could be dehydrated. So drink lots of liquids and don't strain yourself if it hurts a lot.
Actually this is my precious pregnancy as I lost my twin boys after 15 days of their birth which I delivered at 31st week.I got so depressed.I m now on progesterone injections and very afraid.I cant bear any loss again.
I could be growing pain as the baby grows he or she will push against organs. I would tho recommend speaking to your midwife she should examine you and the baby making sure your both ok it's what she there for. Good luck
Sounds normal. Drink some water and lay down. That should help. If you're in utter agony then call your doc. But I think you're just getting to the uncomfortable part of pregnancy.
