so ladies, I've been experiencing what I think is braxton hicks. I'm not completely sure though. I'm 27 weeks and this is my first so I'm anxious a lot. bur, I've been having at least be teen 4-5 contractions an hour and I don't know when there coming or going because I can get them 6 minutes apart or 15 minutes apart. I'm just concerned and don't know if I should be calling my doctor or if that's normal
