Pelvic and vaginal pains at 31 weeks call doctor or no?

Amber

Hey yall, I am currently 31 weeks and 2 days prego with my second child. I have been having pains all week and this morning I woke up and my vaginal area hurts so bad especially when I walk. I'm also having sciatic pains on my left side, but I know that's normal. Just worried about the pains in my pelvic and vaginal area and it feels like I need to go to the bathroom all the time. Like alot of pressure. Is this a sign of early labor or just stretching? and yes I am calling the doctor, just wondering if anyone else has experienced this.

Thanks
