A doctor has provided 1 answer
Conception ?: With an LMP of "05/05/18" and an ultrasound on 06/15/18 showing fetus at "5w6d", the probable conception occurred between May 17 and May 21, which allows for the life of viable sperm occurring just prior to ovulation, and the length of time the egg is available for fertilization.
