As a ftm I feel like I have no clue what's going on. I've been super uncomfortable since Friday night. I get a tightening sensation in different parts of my abdomen several times a day. It stays tight for about 30 seconds or so and then releases. It's not exactly painful but it's definitely not comfortable. It gets worse when I'm exercising. I'm assuming these are Braxton Hicks? I'm 36 & 3.
