Pregnant and 2 possible fathers

I know it’s stupid and I already feel like shit about this, but I need some thoughts/opinions. Last night I found out I’m pregnant, it would be my second. My first is a year old. First day of my last period was September 18th, lasted four days, typically I have a 29 day cycle. Had sex with person A within the first week of coming off my period, my predicted ovulation day was October 3rd, had sex with person B on October second, and had sex with person A again on October 6th. Person A came inside and person B pulled out, but from calculating I really think it’s person Bs. 99% sure I implanted on October 10th (had crazy back/stomach pain that went away the next day, literally the only reason I even tested). Got a positive test last night, so October 13th. I feel like if it was person As it would be from late ovulation and it would be unlikely that I would even have a positive test yet, can I get some other opinions?? I know paternity test will be needed, and if I choose to follow through with the pregnancy I’ll definitely be getting one. Just to clarify, I didn’t cheat on anyone and neither of them are the father to my 1 year old.
