Hi, I took Cerazette for 5 months last year and experienced irregular bleeding and stopped taking it. I decided to try it again and began taking it in December. I was fine for the first 3 weeks of the first packet but started my period a week early and have had constant bleeding ever since! It is generally medium to light but constant throughout the day and goes red to brown and just when I think it may stop goes back to red. I have tried doubling the dose and am on my 10th day but still bleeding!!! My period would have been due last Friday so I am hoping this may be my period but today it has gone back to red and I have some mild cramping so I am losing hope that it is going to stop!! I thought the double dose would stop it but now I don't know whether to persevere or just give up altogether!
