Sex on last day of period

I had sex on the last day of my period which was Feb 14. We started with a condom that broke and then finished without one. He pulled out just before he finished. I began a new birth control this month. Since then I have been feeling extremely bloated especially in the lower part of my stomach, my boobs have been extremely sore, and I just started to spot light brown. I am due for my period in 5 days. Can I be pregnant?
