Could I be pregnant??

I had my period this month. After My period ended, Me and my boyfriend had protected sex 3 days later. After he cummed we did it a little longer. I was on top. He noticed the condom was off and we couldn't find it. I then reached in my lady part, felt and pulled out the condom. His jizz came out inside me. A day later I started spotting for a few days. Stopped, and today I started spotting again along with this white looking stuff. I'm not on birth control anymore Bc I kept feeling sick. Is it possible I may be pregnant?
