Iam 28,76kg.On 23 January 2011 i got my last 3 month Depo shot..have not had my periods since November 2010.On July 11 2011 had my pap smear,cervix healthy,slight inflammation,am on polygynax for the next 12 days.On sunday 17 i had nasty cramps with a few brownish blood drops and that has gone on till today(3 days now).Is this an indicator that my periods are back? I am trying to concieve...should i wait till the ploygynax dose is over as it is contraindicated in pregnancy? and when can i start my folic acid? thanks
