I had them last night for the first time it was painful I wanted to cry I didn't get any sleep...
I mean like unless they get worse and constant lol should've specified.
I'm about 24wks and have gotten atleast 3 or 4 BH over the course of about a week. Don't worry unless it doesn't stop.
Bh contractions always start around 22 weeks for me. As long as they don't come in a rhythmic pattern and intensify you're fine :) but can get rather uncomfortable at times
