Weird vagina pain?

So I'm 35 weeks exactly today...I haven't had any examinations to check my cervix or anything (that starts at my next appointment) and I woke up this morning having really weird vagina pains...it feels like my muscles are stretching or something. I've been having contractions for the last three days, but nothing too serious to make a visit to L&D. Anyone else have these weird pains too?
