Could I be expecting? (I know it's a long story but bear with me)

This was only my 2nd time having sex. And I don't even know if the first time counts because It hurt so bad I made him stop and I don't know if my hymen broke. But anyways.... on my first fertile day of the month, i had sex with my SO. This time he said he could only get about an inch past the head of his penis in and then I remembered that he wasn't wearing a condom and LITERALLY 1 minute later he came but barely pulled out in time. I've been having pregnancy symptoms ever since. Today (5 days before my expected period and 2 weeks since we had sex) I woke up with soreness all over my upper body but specifically below my sternum, the muscles of my breasts, and my sides and belly muscles. Could I be pregnant???
