Hello and welcome to Healthcare Magic. Thanks for your query.
Post-coital bleeding (i.e. bleeding after sexual intercourse) in a woman above 40 years of age needs to be evaluated properly as it can be due to problems of the cervix
, vagina or uterus
. Moreover, since you do not report ant apparent trauma or pain, it all the more warrants further assessment. So, I would advise you to consult a doctor, for a gynaecological examination and further investigations, if necessary.
