I have a friend who is due in September/October and she asked if I've had any Braxton Hicks contractions yet. I told her no I haven't, and she asked me if I knew how many an hour were normal. I told I wasn't really sure, because I've not had any I've not really looked into it. She told me she's had 7 in the past hour. That's not normal is it? Should I tell her to go to the ER? I don't want to make her worry over nothing
