for about 3 weeks. 12 days before my next shot I started bleeding had the shot and then I started very heavy bleeding like standing up and gushing, alot of blood clots. I have now been bleeding for 2 1/2 months and they are heavy most of the time lately but sometimes its only in the morning or the evening. Dr. says to stay on it and I will eventually quit I am 47 yrs. old I have had my family, I started using this because of heavy bleedings. Should I stay on it or stop I'm aiming for stopping at least my periods were only 7-10 days long instead of months.
