Hey I'm Sabrina and I am 20 yrs old I just wanted to know what can cause lower abdomen pain and bleeding during sex. The first time it happened the bleeding stopped 30mins after then the pain started than the second time a week later tried it again and started bleeding 5mins into it than the bleeding stopped again then the pain came after again I would rate the pain on the scale 1-10 a 5 sometimes a 7. Can someone please explain what is going on.
