Could I be pregnant? Partially lost my V

Me and my bf had a first round of oral sex and made each other cum. We wiped ourselves and got dressed.

But I got really horny again 10 mins later and wanted oral sex again during that process he touched on his penis. But then I wanted to feel his dick inside me.

Then he put on a Condom and he was only able to get the tip. He tried going in farther but couldn’t really cause I’m really tight . We tried a few mins but then we stopped.

Do you think I should take a plan b to be safe? . My period is due in two days
