Making a baby with my husband❤

Lavisa
Hi all...I have been using this site to track my ovulation.because me and my newlywed husband and I were trying to get pregnant after many surgeries i have had to my uterus. Unfortunately a week ago today my husband passed away in his sleep from pneumonia. I am still staying prayerful that i am pregnant.and continue to use this site, but anybody know how long the (Sperm) stays in ur body after sex? I am hoping that i am pregnant..any suggestions?
