Hi, I have had regular periods for the last two years. However my Doctor has suggested using the pill as I have been bleeding after sex and she believed this would help. Since starting the pill 30days ago I have been passing brown like substance for about 25 of these days, and three days ago, I passed a tissue like substance that look a bit like steak and was stretchy to touch. Since then I have been experiencing terrible stomach cramps and bleeding. I'm still taking the pill at this point. Has anyone experienced anything like this? If so please help. I rang the doctor and they don't have an appointment until 18yh February and I'm really worries. They suggested a&e. Please help
