i am 34 weeks and 2 days preg, and toinght, about half an hour ago, i got a really sudden feeling of intense nervouseness, and i have never experienced this before. i was just watching tv when it came on, and wasnt thinking about birth or anythingstressful. i was actually quite relaxed. it was really sudden. and i went to the bathroom, and i dont know if maybe i am being paranoid, but i know my body really well, and my vaginal opening feels larger. is this all in my head or could something be happening? i am also getting really bad aches and pains in my pelvis, back, butt and vagina.
