I have had two babies one in 2007 and one in 2008 i have recently got the depo shot in december right after i gave birth before the 3 months was up in february i had gotten the mirena.i bleed for a while then i stopped bleeding well i lost like 5 or 6 pound and now i'm gainig and it seems my belly is lookin bigger. Is it possible that me having two different types of birth control would have cancelled each other out and i could be pregnant again?
