I plan to ask my doctor next week but am curious if anyone else experiences this. Every time I go for a walk around my neighborhood my uterus tightens and feels heavy the whole time. It won’t let up until after I get home and sit around for a while. They say you shouldn’t experience more than 6 Braxton Hicks in an hour. But is constant belly tightening for 15-20 min straight a Braxton Hicks or something else?
