Ok, so here's the deal. I was on one type of pill for over a year and I decided I needed to try something new, so I stopped taking it. I was off of it for 2 months and then started taking a new type of pill. The problem is I have been on the new type of pill for 2 months and I haven't had a period yet. Nor did I have a period during the time I was off of the pill completely. I know i'm not pregnant, but I just don't understand why i'm not having a normal period. I am spotting a little the week before i'm suppose to have my period, but then nothing during the week I should be having it. Also, if i'm not having my period does that mean the pill isn't actually working yet? I'm not sure what I should do. Thanks!
