Worth the worry?

I had sex on my predicted ovulation day (based on this app) we used condoms from beginning to end. He took his thing out after cumming so he was still hard making sure the condom is still intact. He removed it and we waited for 5-10 seconds then we checked the outside of the condom & it was complete dry.

My last period was 9 days late & it was February 17. It's already March 16 and Im not experiencing any PMS symptoms. My next period is due March 17.
