34 weeks and for the past day or two I've been having bad pain down in my pelvic area, almost like the actual bone hurts. It's only gotten worse tonight and it hurts to sit down to use the restroom just about and when I turn at certain angles when I'm laying down. I read that pelvic pain is normal but gosh this sucks
