Pinching & bruising feeling

I’m 29 weeks pregnant, and I have had this terrible pinching and bruising feeling in my pelvis. (pubic bone?) I spoke with my doctor about it and she said I need to drink more water. I drink water all the time, and it just seems to get worse. I honestly don’t think she understood me. It’s so painful to lift my legs, walk, and sometimes even sit. Lately the circulation in my calves have been cutting out too.

Side notes: They may be wrong about my due date, because the time I “conceived” was when my fiancé was out of town for a few weeks.

Also, my weight before pregnancy was 120 & I’m 5’2. Idk if that’s important or not though lol
