Braxton Hicks in the 1st Trimester?

Lindsey
I'm 5-6wks and am experiencing what I'm calling "cramping, " but there isn't any pain involved. It doesn't feel like period cramping. It really just feels like a tightness in my belly, kind of like what a Braxton Hicks felt like with my first pregnancy. It's not just in my uterus, but kind of the whole area below my belly button. Anyone else have anything similar? I don't remember having this the first time, but I don't think I'd have know what it was enough to notice it the first time haha. I've got a large subchorionic hemorrhage this time around, so I'm a little on edge.
