I am 27 I have 3 children my youngest is 2 on the 10th of April so in 5 days! after she was born I took the depo shot 1 time that's a three month dose and after that 3 months was over I waited another 10 months to try having the last baby but my periods were very irregular by the time I saw my obgyn on march 12 and told him I hadn't had a cycle in 5 mo so he put me. Medroxypdogesterone or Provera 10mg for 10 days and then off 20 and so on to start my periods so I can get pregnant I started taking them that day after 10 days I started the wait for my period and I read it takesb3-7 days to start but can take up to two weeks its now been 15 days since since my last pill and nothing I took a preg test and nothing so I am at a loss anyone experienced anything like this ?
