Braxton hicks or?...

ATM

I'm 30 weeks & 1 day and I've been getting this same feeling on & off since 20 weeks. It doesn't actually hurt but causes shortness of breath and I can feel it throughout my whole abdominal area. Like she's either pushing in every direction causing a take your breath away feeling or I'm experiencing Braxton hicks which I know is fine. Lasts about half a minute and I feel several a day. I wouldn't describe these as period cramps. What did your BH feel like??
