Okay so i got my period on august 26 2017 but had sexual intercourse 1day Before with my brothers best friend but it was an accident because we were both drunk. I ovulated on the 8th or 9th of september but had sexual intercourse on the 7th with my best friend and im sh**ting bricks of who the father is im hoping its NOT my brothers best friends my brother would hate me forever!!! HELP
If you had sex with your brothers best friend a day before your period started, he is NOT the father. You are at your lowest fertility. There is NO egg to fertilize and won't be for until around day 11-16 of your cycle. Sperm is only viable for up to about 5 days max.
Your friend is the father with almost 100% certainty. You had sex on day 12 with him. Timing was "perfect." A DNA test can confirm.
Hope it helps.
