Ovulation + Pregnancy

First of all I am here to listen and be educated, not ridiculed. If you are against abortion, I respect your choice but this is not the appropriate thread to write it on.

So my last period was July 29th 2020, I then had sex on the 14th of August - using a condom (but I’m still a stress freak) (due to health reasons I’m unable to be on contraception, condoms is my option.)

My fertile window was 9th - 13th of August.

In term of ovulation ... how does it work, within my “fertile window”, where does my ovulation occur? and if sperm entered my vagina on the 14th, I’m obviously always at risk of falling pregnant, but to what extent.

I also took the morning after pill because I’m a hypochondriac & have very high anxiety.

Please feel free to educate me x
