My partner and I used a condom during sex and it slid off into me when I was on top. we went and got a plan b literally less than 20 mins after, my question though is my period started the 25th and ended the 29th, and had sex 5 days after. My Flo app says that was was the first or second day of my ovulation window but my actual ovulation day is the 8th. Will a plan b still work if its not on my ovulation day? Ive had this happen before and i did become pregnant but still.
