So my bf and I are trying to get pregnant, have been for four months, went to my doctor about it she said I have to loose 25 pound (witch is no problem) and to get my periods right on track again, because I took depo for 3 years and it messed my periods up..... does it usualuuy take a long time to get pregnant or something... I'm on the pills but I hardly take em cuz I forget and my period was on time twice already... I dunno what to do!
