So, I'm 18 weeks along. For the past few days I've been getting sharp cramp like pains in my lower stomach. Tonight, I went to use the bathroom and a few small blood clots came out. Really small like the size of a small worm. (Kinda of like what your period can look like at the end when its slowing down?) I've also been experiencing a lot of stress and worry about the baby this pregnancy, I know its not good for the baby for me to stress but for some reason I keep worrying that something is wrong. I wasn't really like that in my first pregnancy. Any thoughts, advice? I don't want to over-react but I also don't want to ignore it. Thanks!
