Miscarriage, Plan B, Pregnancy

Backstory, i got pregnant at the end of Feb and had a miscarriage when i was 6 weeks along (April). I’ve had one regular period since then May 1-5 Now, i had unprotected sex twice (finished inside me) 1 or 2 days before my predicted ovulation date (use the Flo app). I took a Plan B the next morning and had some light spotting about 5-6 days after. My period is due in 8 days. Is there a possibility or pregnancy or should i be good you think?
