Rely on birth control pill only

My husband and I got married last month and I’ve been on the pill for the last year and a half. Never miss a pill and take it within the same hour. Since we got married we decided to let him finish inside me rather than pull out. This is the first month doing that. I take my last hormone pill tonight and should get my period Tuesday as I normally do. I’m nervous I’m pregnant though cuz I’m tired and my boobs are sore. Just need some reassurance that others let their husbands cum and don’t get pregnant on the pill.
