Yes it happens to me alot when i lay on my back :)
There is no pain associates with it. I notice it happens more often when I sneeze. It's random, something like if you have ever experienced your eye randomly twitch
I thought it was one of my organs twitching out lol
Now I see you said upper stomach which I'm not sure about. I can read up and see if I find anything about upper stomach!
I experience this pain as well! They say it's just your uterus stretching. Nothing to worry about. It's actually a good thing!
Thanks! Glad this is normal
Oh yeah it's completely normal. I get them several times a day especially when relaxing.
Omgoodness yes. A few times its completely normal.
