Pregnant or paranoid

I religiously take my birth control and haven’t waved more than 20 minutes off my normal pill taking time in the last month. But on my last pack, I finished my period and still had 2 more placebo pills before the new pack. I finished the placebo pills before starting the new pack and I’m currently halfway through week 2 on that new pack. Could I become pregnant since I had already finished my period when I started taking the active pills again?
