Hi, I've stopped taking my birth control pills for 4-5 days, without the intentions of actually stopping, I guess I constantly forgot to. The first pill I think I missed was on the 19th of this month then took the 20th then missed 21st and 22nd. My period before this was on the 12th which was in the red section.
My period just started again yesterday, the 23rd. I'm just wondering if there's anything wrong? And how I can start taking my pills properly again?

I would start a new set of pills at the proper endtime of your current period. Wait at least a month to have unprotected sex. Maybe insist on condoms if this is a regular occurrence.

"I Guess I completely forgot too." That is a piss poor excuse. I had a friend of mine forget to take a pill. It was at the right time and she got herself pregnant. These need to be used as directed or else they will fail. Please use a secondary form of birth control.
