Im almost 16 and my periods usually pretty regular, but

Patient: Im almost 16 and my periods usually pretty regular, but it’s been very irregular for the last two months, and I’ve been spotting on and off. last night I was spotting and I also had unprotected sex twice, last night. the first time I’m almost positive that he pulled out the second time he didn’t. And he cummed both times. I’m not on birth control either. But because my cycle is messing me i’m wondering what are the chances of me being pregnant. Could I be pregnant?
