condoms or naw

So I am on the pill and have not missed a pill or taken one late this entire month. Ever since about two months ago, my guy and I always used a condom as well. But then we talked about it, and decided that if i take my pills well, he will just pull out. He has never gotten any cum in me. I'm about a week before my period and I'm already having symptoms like cramping and sore boobs? I'm afraid I might be pregnant or something. I know I sound stupid but this is the first time I've gone a month without using condoms so I'm a little paranoid.
