 This is my second pregnancy and I'm 23 weeks. I've been having a lot of RLP in the pelvis crotch area. I mentioned it to my doc. He said that it was typical in second pregnancies because things where as firmed up as the first time. 

 But today it's really bad. I sat most of the day, so it's not like I over did it or pulled something. The pain/pressure is in my pelvis and crotch but it is kinda inthe middle and on my right side. It hurts so bad it makes me almost nauseated. I tried to pick my foot up to slip my tennis shoes off and it was crazy painful. 

Is this normal for a second time pregnancy?
