I'm only 5 weeks but I get them too and it's just your body moving around for the baby
You can actually get braxton hicks as early as 10 weeks and they actaully start around 6 weeks but most women just don't feel them until later on in pregnancy, with both pregnancies now ive started getting them around 13-14 weeks. Totally normal, just watch for spotting or bleeding which isn't normal!
I meant 20 weeks not 29 weeks I'm sorry.
Braxton hicks/stretching... unless you start to spot/bleed dont stress... call your doctor and speak with him/her.
I had braxton hicks from 22 weeks so could just be that feels like your about to come on your period X
Those are Braxton Hicks contractions. They can start as early as 29 weeks.
Im nearly 24weeks and get them all the time. If irregular and quick most likely stretching.
