I'm 32+3 yesterday and today I threw up a lot and in the throw up there was these black string like things. I haven't ate anything with that. Thursday I did eat a shrimp and fish stew, and then oatmeal afterwards. Friday I ate pizza in the afternoon and today I made pork chops, mashed potatoes and green beans and then I reheated some pizza. Idk where the black things would come from. I'm freaking out and my baby stared hiccuping right after this was about 20 mins ago and he hasn't kicked.
