Condom while on the pill?

Regan

I know it’s better to use a condom and be on the pill, but if you’re on the pill and he doesn’t use a condom, does he have to pull out??

My boyfriend and I normally use condoms during sex but I’m about to start the pill and I wanted to know if we still needed to use condoms too. After the first week of being on the pill could we have sex and him finish in me without me getting pregnant?
