Is this normal???

Carolyn

So I'm 23 weeks and I've been having these abdominal cramps on and off for the past two days. My stepmom told me they were Braxton hicks but I've heard those aren't supposed to be painful and I thought you weren't supposed to have them until you're in your third trimester. At first I just thought it was gas or constipation or something but it's not. I'm a little concerned with how frequent and painful they are. I had 6 of these cramps yesterday and about 4 or 5 today. Is this normal? Should I see a doctor? My next OB appointment is in 2 weeks should I just wait?
