I take my pill at 6pm every evening on Thursday I took my pill as normal and then on Friday morning at approx 10am I had one episode of diarrhoea I then continued to take my pill as normal Friday Saturday and Sunday at 6pm then on Monday morning I had another one isolated episode of diarrhoea at about 11am. That evening I took my pill as normal and then later I had sex with my partner without thinking that I might not be protected.....now I'm worried I wasn't protected is that possible? Thanks
