Hi Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concern.. Most common cause of light spotting after having sex is bleeding from cervix ( the lower part of uterus). Cervix has high blood supply & Even when cervix is healthy, vigorous sex can cause some bleeding. This mostly occurs when you have vaginal dryness or less vaginal lubrication. Vaginal dryness is common in elderly women & especially who might be undergoing menopause. Menopause can also cause delay in periods. Menopause is a life event in a woman s life (typically between 40-50 years of age) when she stops ovulating & hence menstruation ceases. Menopause causes deficiency of oestrogen in a woman, which could be responsible for vaginal dryness. However bleeding from cervix can be because of some abnormality in cervix. In case of cervix abnormality, even gentle sex in presence of enough vaginal lubrication could cause bleeding. Therefore a Pink spotting could be a sign of cervix abnormality. As you have bleeded twice, so there are chances of some cervix problem such therefore You are advised a pap smear to rule-out a cervix problem. Refer to a gynaecologist. Hope this information helps
