I'm 30 weeks with twin girls and had my last checkup yesterday. My OB asked about Braxton Hicks and I said yes. She told me to start keeping track, and if I have 4 or more in an hour she wants to know about it. Problem is, I can't always tell if I'm having one. My belly constantly feels tight because I'm getting big, and sometimes I can't tell if it's contracting or that's the babies moving. Any tips for differentiating a contraction vs. normal aches and pains or movement? If I track everything I think COULD be a contraction, they'll probably put me in the hospital for observation and I don't think that's necessary at this point. Thanks!
