Is it ok to stop taking birth control ?

I am 21 years old and have been taking birth control ( yasmin ) for a couple of years. My doctor put me on it for medical reasons , horrible cramps , migraines , heavy flow etc. But it hasn't really helped that much besides helping my acne. I still have really bad cramps and migraines.I recently had some problems with my insurance and wasn't able to get my birth control pills. I have been off of them for about a week now. I am not ually active I'm still a virgin and my periods were never that irregular so I thought it might be ok to not start taking them again. I was wondering if any of you have had similar problems. Any advice would be appreciated.
