I'm 29weeks now, and mine JUST started becoming noticeable recently. I know I've been having them for a while because if I put a hand on my belly, I could feel it tighten up, but they weren't strong enough for me to feel from the inside until about 26 weeks or so.
When you feel like the baby is sticking up in one place and u feel your stomach tight, those are Braxton hicks. They aren't going to hurt.
I didnt feel them until 30w with my first, she was born at 38w. With my second, I started having them at 17w. He was born at 36w.
Some people never do..like I haven't, I'm also 33w
I never experienced them. Its nothing to worry about (:
It feels like your belly is tightening. I experienced light cramping once with them but mostly I would just experience the tightening
I'm 33 weeks and I haven't noticed Braxton hicks.
