I dont really pay attention to it because with my other daughter it turned out to be Braxton hicks but now you left me thinking if I keep having them I'll have to go check everything is ok. thank you both.
I have a friend and around that time she started having contractions and she went to the doctor and she was dialated so they had to give her a cervical stitch and she needed to be on bed rest. I'd say call L&D and tell them how far along you are and tell them you have contractions and see what they say. I wouldn't wait it out to see just because it can be normal and nothing to worry about.
They may just be braxton hicks! But if they continue... id go to the hospital.
