I'll explain what is going in your body!
I am educated in womens health actually
you are like me, one of the 'lucky' women that bleed all the time with a birth control method like depo. Some women will lose their periods completely, some will have zero change, and a few will have everyday non stop bleeding.
I did not use depo, I used the mirena iud, which has the same hormone and effects on the uterus as depo.
Basically, depo thins out your uterine lining and stops ovulation, as you fully know I am sure. In some women, the thinning out of the uterine lining can be so much that it is like an open sore..It keeps bleeding. That is basically what happened..
It takes about 6-9 months for depo to get out of your system, it has a very long duration..
