What are your opinions..

What are the chances of getting pregnant if I had unprotected sex with my hubby the first morning of my ovulation cycle if I were on the pill for a week and about 6 days but stopped taking 1-2 days before we had unprotected sex due to conflict with a medication I was given. I had like a light pink color in my discharge when I wiped on Wednesday I think it was and I’ve never had spotting during ovulation and I don’t ever remember having spotting when I conceived our son (who’s now almost 2)
