HELP A SISTA OUT

Soo ... I practice safe sex and one time my boyfriend and I had unprotected sex and he just told me he might have got some of his cum in me. I’m so pissed my cycle is suppose to be here on the 1st. Yesterday I had light bleeding, but we had protected sex (I made sure nothing got in my this time ) 😂. I stopped spotting. Could I be pregnant ? Any comments. I’m going to the doctor Thursday.
