I was on the depo shot for 1 year. The last shot I got was in august 2010. It lasts 3 months so it should of been out of my system LAST november! I started my period for the first time coming off depo thios past May and that period lasted me all month! I had no period this past june. But had a normal period in july and august. Now its november and I haven't had a period since august. And all HPTs and blood tests are negative! me and my husband have been ttc since March 2011 and no success! So my question is, after your doctor gave you something to regulate your periods, how long until they started regulating? Then after they did, how long did it take you to get your BFP?
