I had a period on 12th June lasted 6 days then on the 5th July I had a very light bleed manly brown discharge lasted only one day. On the 20th July I took a pregnancy test it was negative now the 1st August the same even lighter bleed this time only brown discharge. I have been taking cerazetta (mini pill) for 2 and a half years and normally I bleed two weeks on 2/3 weeks off. have been getting bad headaches and am very tired all the time. Any advice would be great
