Yes! Go to a gyno for the right help
Hi,
Bleeding after sex is not normal, unless this happened to be your very first time having sex ~ although the bleeding shouldn't be as heavy as a period. If you don't believe the bleeding is caused by an irregular period, you should see a doctor right away or go to an emergency room. Rough sex is fine, as long as someone isn't getting hurt in the process. An injury during sex, dryness, an infection within the vagina, polyps, etc. can cause bleeding, but can be treated by a doctor during a pelvic examination. Bottom line, get checked out by a doctor if this has you worried.
