Hi im 20 years old. I have been on the combined pill since I was 16 and have never had any side effects including no vaginal bleeding other than in my monthly break (my period). The last 2 months I have had sex four times with two different sexual partners and I have bled during sex. It is not painful but it seems every time I am having sex I bleed. The most recent time I have bled a lot that I had to stand in the shower and continued to bleed afterwards until the next afternoon. it has ruined my confidence and I am unsure what it is. I have had a full STI check twice in the last couple of months and both were negative.
I hope you have some advice on what could help.
