a month ago. i had heavy bleeding that lasted for a month, just two months after i had my son. the doc gave me birth control pills called yasmin. the strongest birth controll pill to stop the bleeding, or make it a normal flow, after a day or two the bleeding stopped, and two weeks later, well last week i was off the pill for three days, and i took them agian, and i started to have heavy bleeding, and foul smell, im wondering what it might be.
