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?

It is most likely to be your husband's child.  But it would not hurt to get some confirmation.  In your position I would go right away to a doctor and get an ultrasound scan, since ultrasounds early in the pregnancy can help to confirm when the conception was.  Tell the doctor that you would like to know the estimated due date based on the measurements of the embryo and its developmental markers, not on the first day of your last period.  Then take the estimated due date home and plug it into an online conception calculator (or count back 266 days on a calendar).  That will give you an estimated conception date.  

Counting from your first day of your last period you are presently 7 weeks 6 days along.  Don't delay or the ultrasound won't be that useful to try to confirm your conception date, because as time goes by, babies grow at different rates.
