I've been taking camrese for about five months for about 3 weeks i have been bleeding and spotting every day. so how much longer should this last?

Unusual: If you have been taking this birth control pill for 5 months without a problem, and now suddenly have bleeding for 3 weeks straight, then the possibilities include: 1. Normal side effect of the pill related to extreme thinning and fragility of the uterine lining 2. Pregnancy - check a test 3. The presence of something like a uterine polyp this is a great discussion to have with your doctor.
