So, last night I laid down in bed then remembered I needed something (probably had to pee). When I went to sit up, I noticed that my stomach arched up. I laid back down, pulled my shirt up, and repeated the movement. My stomach actually formed a triangle!! Midline of my stomach and a few inches on either side bulged up and formed a triangle of sorts out of my stomach. I waited until DH came in the room, did it again, and we both laughed at my alien belly. I didn't think anything of it again. Until tonight. I googled it. Those 3 words, "I googled it," are like a four letter word to a paranoid pregnant lady and should cue horror movie music immediately.
Turns out it's real and has a name, Diastasis Recti. Basically what I've found out is that due to the hormone relaxin, the connective tissue that holds the abdominal muscles together is relaxing and therefore causing the seperation and therefore the triangle look. Most of what I have read says it's normal but what varies is how it heals. I've read that sometimes it heals just with exercise or sometimes requires surgery. I've also read that it may result in hernia.
Needless to say it has freaked me out and I have backed away from Dr. Google and am happy that I have an appt with my OB Wednesday and can ask her! Just curious to see if anybody else has this or has had it with previous pregnancies and what happened after you had the baby.

Re: Triangle Tummy
Sorry for rambling, trying to come up with a rational explanation rather than just accepting that I really do have a Prometheus in my belly!! >-)
Very interested in discussing this with my OB Wednesday!
