What is going on here? Haven't had my period since early to mid November. Took a test early December that showed positive. Took another that showed negative. Figured I'd wait it out. So it's now Jan. 4th. Well last night I had a really bad reaction to something I ate. I always have cramping when this occurs. It typically results in a bowel movement. Last night I could not have one. I had the same symptoms that I usually have, which are itchy hives all over my body, swollen hands, feet, and lips, etc. So I took a generic claritin. I had some cramps in my uterus ares, I think. I feel asleep, very worried of course. I woke this morning and used the bathroom. I had some moderate blood and what look like really thin tissue like clots. Clots were really thin. I cleaned up and went to work. Once I got to work and the rest of today I have not had any more bleeding. I really need to know what is going on. I would think if it were a miscarriage I would have more bleeding. It was enough blood to make me worried, but it was there and gone. I heard miscarriages are similar to a heavy period and this was not for me. My periods are very heavy and this was not. Please Help!
