I am 13 weeks pregnant. Today, while I was having sex I got a slight stomach ache. Immediately after sex, I didn't notice any bleeding. About 1/2 hour afterwards when I went to the bathroom, I had a fair amount of blood on my tissue. It was more than spotting; kind of as if I had my period. I called the doctor on call and she said I could either wait and see if I stopped bleeding or go to the emergency room. She explained that I might have broken a blood vessel and didn't seem too concerned overall. It has been over 5 hours now and while I have no crampinig, I have slight spotting still. Has anyone else dealt with this? Should I be calling the doctor again?
