When I was on the pill I had the same issue, I think it might just be the hormones in the pill that reduces your period to nothing, over a period of time.
Thank you so much for the advice. i was going to do what you suggested and wait til the weekday to call my doc but then it all kinda went back to normal somehow...i think my body just likes to scare me. lol
When I was on bcp for a long time I had much lighter periods and then when I was using the injections depo provera my periods stopped all together. Best thing would be to call your prescribing doctor telling him about the change you are experiencing. Then you will have piece of mind that everything is ok.
