Please don't judge me ! I had 18 month affair which ended in June 14! Got back with my husband and came off protection ! Last period was 14 sep 14 and a moment of weakness slept with other man on 16 sep ! I then went on holiday with my husband on 24 sep and had sex 4 times on that holiday ! Took preg test on 15 oct 14 which says I am preg and conception was 2 -3 weeks ago ! I know by looking at ovulation calc that my fertile period was on holiday ! How can i be sure it is my husbands ? Wondering if best to terminate so I don't wreck my marriage ! That is my main concern ! Any thoughts greatly received
