Sooo

Thursday I had sex I’m on birth control and we don’t use condoms but he pulls out. He didn’t ejaculate before only one time when he pulled out. I’m nervous because I have been having what feels like ovulation cramps but I have no cervical mucus or anything! I take my pill EVERYDAY at 7pm on the dot and I’ve been on the pill for 4 months! Should I be concerned?! Never had a problem while on bc before
