My LMP first day is Feb 2 2015, I took ovulation test Feb 13 2015 at approx 3pm and got a smilie face. My husband and I had intercourse Feb 13, 14 and 15. I then had an affair with another male and we had intercouse Feb 21, 2015. I took a home pregnancy test March 2, 2015 and it was positive. I took another one same day and the display read pregnant 2-3 weeks. What are the chances my husband is not the father?
