How effective is the Pill?

J✨

Ok, so I’ve been on BC for almost 6 months now. My SO & I have unprotected sex & he finishes inside me.

Now, I know that the pill is 99% effective. But I’ve read a lot about it & it kinda gets me anxious.

Basically my question is, if I were to get pregnant on the pill, would I still have my period when I’m on the placebo pills or would I miss it?
