I have been on the same pill for about 4 years now and not had a problem before. My last period lasted the whole 7 days heavy when usually I'm only on for about 4/5 a week later after restarting my next month of pills I get stomach pains & start bleeding very heavily for 3/4 days now.. I get really bad headaches and a slight fever every now and again and just generally don't feel myself... I went to the doctors who was a locome & told me he wasbt going to do anything but reassure me it's fine & if it carries on for the next 2 months to go back!? But could I possibly be pregnant as me and my bf have recently got back together and have obviously been quiet active!!
