Sperm from 14 days of abstinence does not have much to do with being able to get pregnant, you need to consult your doctor.
For men, the quality of sperm is better when abstaining from sex for about 3-7 days, and too long or too short of an abstinence period can have an effect on the quality of sperm. Too long a period of abstinence will reduce sperm vitality, while frequent sex will lead to a decrease in semen count.
Normally, a woman ovulates in about 10 days. A woman will only ovulate one or two eggs every month, and the eggs will survive in the body for 1-2 days. Therefore, only by having sex when the woman is ovulating, the man’s sperm will have a chance to combine with the egg to form a fertilized egg and achieve pregnancy.
Pregnancy is related to both men and women and cannot be solely based on the time of abstinence of the man. If there is a need for procreation, sex should take place during ovulation.
