Any opions would be appreciated. this is my 3rd pregnancy and so far the hardest. a few nights ago had some love making with hubby and afterward had contractions about 2 min apart and like 40sec long. they went away after about 40 min. I have a lot of pelvic pressure and pain and baby seems really low. the last few nights havr been so uncomfortable to sleep. super sore and so hard to move. I'm only 34 weeks. should I call doc to be safe or is it normal?
