This is my first time on birth control and I was told to start Tri-Sprintec as soon as I was done with antibiotics which happened to be 12 days into my ~32 day cycle. According to my period calendar I started ovulating on day 14 of my cycle and ended ovulating on day 20.
My natural period was supposed to start today which is also the same day as the placebo pills begin.

1. My question is basically WHEN am I truly protected?
2. Am I protected after my period?
3. If my period doesn't come during the next 7 days do I start the new pack regardless?
and the question everyone wonders: when can I start having unprotected sex with my fiance?

I know it is a lot of questions :( I've searched near and far for answers but everyone is unique!

Thanks so much in advance everyone!
