Bleeding During Intercourse, Straining During Bowel Movement. Taking Birth Control. Ultrasound Normal
There can be many reasons for bleeding during intercourse like
Vaginal wall injury
Inflammation of cervix and vagina like
Cervical erosions or atrophic vaginitis
Infections like
Chlamydia
Gonorrhea
Trichomonas
Yeast
But they are associated with other problems like vaginal discharge,burning,itching etc
Abnormal growths in vagina like vaginal polyps
Cervical cancer in cervix
Uterine polyps,uterine fibroids,endometriosis in uterus
Although endometriosis and erosions may cause bleeding during bowel movements,it should be made sure that they are not coming from rectal reasons like hemorrhoids or anal fissure
You must consult your doctor for
P/v examination
PAP smear
Colposcopy etc.
Once cause is known,treatment can be outlined
