Don’t really understand”ovulation” in my case, emergency contraceptive

Hi,

New to this.

Yesterday evening me and my longtime boyfriend had sex, he came inside and after sex we realised the condom was broken at the tip the entire time (heard a quiet pop at the start of but dismissed it as we 100% of the time hold the tip and put on the condom properly). 3hrs after the sex i took the ellaone pill. Ovulation tests done yesterday were negative,( today as well) sore breasts and high temp were present plus i have no discharge. i went for a pelvic ultrasound today morning and the doctor said there is a 16mm ovarian follicle and that the ovulation is today. did Ellaone have any effect since it only works by delaying ovulation? Sorry for any mistakes but I’m in a terrible mental state (hard financial situation as I am freshly done with my college and with no familial support ) and can’t think clearly
