If I take two pills instead of one would that protect me more if my boyfriend ejaculates inside me?

My boyfriend wants to cum inside me and I’m scared. So far we’ve been taking precautions, I’m on the pill and he wears a condom. I’m taking the Yasmin 21 mini pills and I’ve been taking them for about two months now, I always try to take them in time although sometimes stuff gets in the way and I end up taking it later in the day but I never miss it. We both want to try this but we’re scared something will happen, I’m in college and a pregnancy is the last thing I need right now. Would taking two pills a day help? Please no mean answers, i am genuinely clueless, girls helping girls is what this app is all about. Thank you.
