Could I get pregnant??

I got my Nexplanon out 2 weeks ago. I started my birth control pills for 2 days and then I got my period so I got my period and then continued them.

I have taken 8 birth control pills after my period.

My fiance and I are both clean and didn't use condoms before on Nexplanon.

Can we start using no condoms (finish in me or not)? Or should he just pull out?
