Hi!you could be having something as simple as an erosion on the cervix
.erosions cause the outer part of the cervix to become very vascular and are a result of plain hormonal
),or infections .postcoital bleed however warrants that you go to your gynaecologist and have a pelvic clinical examination and a pap smear/liquid based cytological testing done to rule out cancer,precancerous lesions ,HPV
testing and also know the cause of such bleeding.Also your doctor might advise colposcopic biopsy
of the cervix if pelvic examination shows a suspicious lesion in the cervix/or if the LBC report is abnormal .
