I am 19 years old, and I have a boyfriend which I am currently having sex with. At the beginning we used condoms, which there was no problem at all. I decided to go onto the pill, microgynon 30 which I havebeen on before when I was younger as it helped regulate my irregular periods. I followed the instructions on the leaflet by taking my first pill on the first day of my period. My periods have always lasted approximately 4-5 days but now I am on my 8th day of bleeding and it doesnt seem to be stopping. It appeared that my peroid was nearly finished and my boyfriend and I had sex using condoms, which resulted in bleeding after. I am so worried that there might be something seriosuly wrong with me as I have never experienced this before. I have also started exercising regularly by going jogging. Could this possibly be a reason?
