Just saying but I am 17 weeks and I'm going through the same thing where your whole back and you just feel like everything is about to fall out it hurts so bad when I went to the dr basically I found out I had a urinary tract infection I'm taking meds and I'm not saying you do have one but it's a possibility cus I was experiencing the same kind of pain maybe ask your dr.
Its true we all go thru diff. Symptoms. So my experience may mean something diff. From yours. So its safer to consult your dr to be on the safe side. Just don't worry too much. Pregnancy is always full of mysteries and surprises. Gud luck.
I agree with lifesjoy23. I'm pregnant with my second and the pain in my lower abdomen is much worse than it was with my first. My doctor insists that it's ligament pain and by uterus growing for and with my baby. Call your doctor and see what they suggest you do. Good luck.
It may be your uterus enlarging for the babies growth, but my mid wife said if presence in pain can be baby in distress. Please go see a doctor
