Birth control effectiveness!? help?

I haven’t missed a single pill of birth control, and I was wondering how effective the birth control was even when it’s towards the colored pills. My boyfriend had finished inside the day before I was going to start my colored pills and I was wondering if I should be worried about being/getting pregnant since it’s right before I’m supposed to start my period.

I’ve also been taking them at about the same time everyday (within the 4 hours that I first started taking it. I started at 10 AM. So, I usually take it either between 8–12). But, have been taking it at around 10 AM every day.

Also; I’m just took my third colored pill today.
