bleeding after sex

ok. about 3 years ago, I had an abdominal myomectomy for endometriosis.. earlier this year I had a hysterscope for uterine fibroids, and this was 3 months after my last lupron injection. I had af for the first time on last month and this was with the help of provera, so that I can start back ttc. now im experiencing bleeding after sex, mostly during my fertile days... has the bleeding happened to anyone else???
