u/Better_Title_9307

So I know apps like Flo aren’t the most reliable but my projected ovulation phase was April 19-28. I had protected sex without any incident. On May 3rd my boyfriend and I had a protected sex when he pulled out he noticed part of the condom still stuck in me exterior was hanging out and some on his private part. To be safe I took a plan b within 30 mins. My expected period date was may 9th should I be worried or concerned. I need serious advice
