Hahaha question

So I feel like a dummy asking this because I’m 21😂 but I’m on the pill have been for about 2 months do I still need to use condoms? Like I’m not worried about an std because my fiancé and I are with each other. I’m more concerned with the pregnant part. Since I’m on the combo pill and take it correctly is the condom necessary or am I protected from pregnancy being on the pill? I know nothing is 100%.
