16 and BC pill

I’ve been w my bf for almost 2 years. When we have sex we sometimes use a condom but sometimes don’t. I’m on the BC pill and I take it on time everyday. Also if we don’t use a condom he always pulls out way before cumming. Btw him and I both don’t have STDs which is y we don’t always use a condom. I just wanna know it u ladies think I’m being safe? Ik there’s always a risk of pregnancy but do u think my chances r slim enough? Anyone else use the BC pill + pull out method?
