12 week pregnant, what could be wrong.... 
I've been having some chest pain just feels really tight not sure if that has anything to do with it but... 
I woke up this morning and my stomach was feeling weird and I thought I was just hungry, after I ate I went to the restroom and there was quite a bit of blood that came with a bowel movement.
It wasn't from the baby or anything, for sure from the bowel movement... 
Any nurses or anyone that has experienced this being pregnant???
