I'm 18 weeks today and about 3 days ago I experienced a severe sharp pain in my stomach. I was laying down on the bed and tried to get up into a sitting position quickly. When I did I felt a sharp pain it felt as if the babys foot was stretched out all the way and was pushig through my stomach ( if that makes sense) it didn't necessarily hurt , it just shocked me it kind of felt like I pulled something within a minute the pain went away... this isn't the first time I've experienced it, I've experienced it before whe trying to get up before.. I think it might have been the way I got up, has anybody else experienced this ?
