I've been having some tightening in the center of my stomach a couple of inches below my belly button. It is pretty much exactly in the middle and always in the same spot. It doesn't hurt, it just feels uncomfortable. Is anyone else experiencing this?
Re: Tightening in middle of stomach below belly button
Does it feel like pressure and if you push down when its bothering you is it hard? because I thought I was a nut and it Didn't hurt just felt like alot of pressure right there.....Found out today its just our TaterTot being a pain in the tummy
Maybe its just baby!!!!! 
Sounds like a Braxton Hicks contraction.
ETA: Totally normal. These are just practice contractions that don't actually do anything. If you have 4 or more in an hour, call your OB.
Yes, I guess I described it as tightening because it feels harder when I push down. I guess that's why I described it as it feels like my muscles tightening. I haven't felt anything I would definitely describe as movement so its hard to believe baby is big enough to do that. But baby was hanging out in that area when the doctor listened to the heartbeat.
Yes, feels like it's towards the surface not deep down like period cramps.
This! Probably Braxton Hicks, but do pay attention to how often they're happening.
It sounds like BH or it could be where LO is pushing. I get that where LO is, I just poke it a bit until it moves.
