I have an appt today , but I never called because I don't have 4 to six in 1 hr.
agreed^ I was having contractions with out even knowing it and also had to get the shot. thankfully I was in there for a different issue and they monitored me.
If you are having more than 4 or 6 an hour call, if they are regular like if you have them all 10 minutes apart call, or if they start getting stronger call. And really stress your concern. I am 29 weeks amd had to get the trebutaline shot to stop my contractions
