confused much

i beg for you not to judge me. i was diagnosed with PCOS and was on meds for it. i honestly never believed that it would work. i had sex on the 13th of march with my bf and on the 15 with my ex bf. i am now 6 weeks and 3 days pregnant and not sure which is the father 😔. is it a case where its the first person who came inside me got me pregnant? p.s. they both came in me. i honestly am not proud of what i did and i regret making that mistake
