I'm in phase 3 and I've been on the pill through the whole program. I'm curious as to when my birth control should be effective again and so won't have to worry about it anymore. I can't find anything about it just that the diet can make the birth control pill ineffective.

Thanks!

I'd say to be on the safe side you should count it like you did when you first started on the pill. Or this:

From healthywomen.org:
If you begin taking birth control pills within six days of the first day of your period, it's effective immediately. If you start at any other time, however, you need to take it for a full month before it's effective, and you must use another form of birth control until you've completed one full cycle of pills.

Best to check with your doc or pharmacist though if you want to be completely sure.
