I am almost 24 weeks pregnant. I woke up this morning with what i thought was really bad poop pains. I did pass what was a normal poop for me and went to lay down. When i layed down i kept feeling like i had poop cramps and went to the bathroom to feel very hot and lightheaded. I ended up blacking out for about 5 minutes. When i came too i had to use the bathroom again and nothing but blood came out of my rectum. It happened about 5 times and everytime it filled up the toliet. I called my doctor which sent me to triage at the hospital. The hospital ruled out hemroids and did some blood work. They said everything was okay if it got worse come back. That it was probably a gi infection. I am still cramping but blood has slowed down. But im obviously scared because this has never happened and im pregnant. Do you think the doctors are right or should have done more investigating before sending me home?
