Hi, I Had A Vaginal Biopsy On June 5th, Had

Hi, I had a vaginal biopsy on June 5th, had unprotected sex on June 8th I was supposed to get my period the 16th of June, but I got it on the 13th of June I also had sex on the first day of my period but this time my husband wore a condom. I have been a little nauseous, had a bit of breast pain, some head ache, some food cravings a extremely thirsty. Can I be pregnant even though I got my period 5 days after I had unprotected sex?
