Symptoms

Hi I am just looking for a little bit of advice/reassurance really,

A round 4 months now after me and my had intimate relations I started bleeding quite heavily, this lasted around 5 days, since then every two weeks I have a period, I am booked in next week for a smear and swabs, I shouldn't have a infection as we haven't had intercourse for around a year as my partner had ed problems with being diabetic,

Could anyone advice me if this sounds suspicious or I don't have any thing to worry over, thank you, joanne
