I am 15 weeks and 2 days. Last night I was sitting in my husband's truck and when I went to get out, I put one leg out on the ground and stood up and immediately got this pain on my lower right part of my abdomen. It was literally the worst pain I have ever felt, it took my breath away and automatically made me drop to my knees and I had the sudden urge to vomit. I couldn't move, every time I tried to stand up the pain would start up and I would fall back into a curled up ball and get the sudden urge to vomit again. I did some deep breathing and stayed there for about 5 minutes, my husband tried picking me up and taking me into the house but I literally could not move without the pain being so terrible. After about 10 minutes of being curled up into a ball, I slowly stood up and walked to the house even though the pain was still there. I went to the bathroom and noticed I'm not bleeding. It wasn't a gas cramp but I have literally never felt anything like that. After about 20 minutes, the pain was still there but not as bad but definitely flares up each time I move. This morning, I woke up in pain again, but not as bad. I don't know what it could be.
