Hi! I have been taking birth control for two years. I have been taking the three month long pack and then off for five days then begin again. Recently, I only took one pack then stopped instead of taking all three. My question is that after I took one pack and stopped, I never got my period. About 2-3 days after I took my last pill I only got a little dark brown discharge. It's been almost a week since I took my last pill and I still haven't gotten my normal "light" period when I'm on the pill. Is this normal? Will I get my period? Am I possibly pregnant? I should also mention that about a month ago I started taking some diet pills. Could that be the reason to why I'm not getting my normal period?
