No period on the pill

El

I just started my second pack of bc and I never got my period while taking my placebo pills on my last pack, I think it’s normal but I just want to make sure. Should I be worried? I had unprotected sex a few times but my boyfriend pulls out every time. I know there’s always a chance but it’s been a while since the last time I had unprotected sex and I don’t have any symptoms. I’m sure it’s just my body getting used to the hormones but I just wanted to hear some opinions.
