I have been on Loestrin 24 since April 07. I am surprised at all the negative feedback here. I was in LOVE with this pill. I lost weight, my skin seemed better and I was overall happier! My doctor TOLD ME BEFORE HAND that I may stop having my period all together. And I did! I stopped having it about 4 months or so in. Well here it is Dec. 13th. I went off the pill around November 19th (due to the outrageous cost!) and have been waiting for my period so I can start another set of pills. Well like I said I stopped having my period at all on this pill so it was no surprise when in the first week of stopping the pill I did not start my period... well now its been 3 weeks and I still haven't started. Thats what I'm worried about.... WHEN will I start again???
