So I'll be 38 wks tomorrow. I luckily somehow made it up to this point in my pregnancy without morning sickness or anything. Today I woke up with a terrible stomach ache. I started to vomit around 3 pm and it was full of blood. I can taste blood in my mouth. The stomach ache hasn't subsided but hasn't gotten worse either. Is this ob related or more medical? Should I go to the hospital? Has anyone else experienced this?
