Over the past few days my belly has been feeling tight/pulled a lot. The strangest thing is that when I go to the bathroom to pee, right after that my lower abdomen tugs for a few seconds. Has anyone else had this? Could these be Braxton Hicks? In my first pregnancy Braxton Hicks started around week 35, and I don’t recall that happening after going to the bathroom.
