I'm 29 weeks today and have been getting contractions nightly about 10-15 min or so apart. They don't hurt and I don't have any other labor symptoms... It doesn't happen for hours, either, just maybe an hour or two. Is this a normal thing?? I know I should ask my doctor about it but my apt isn't for another week and a half. Plus it's not like emergency status or anything, was just curious if others have had this also.
