I think you were asking if having more sex than just day before and day of will interfere with conception----the answer is no, it will not. You can have sex as much as you want. It also could help because you never know the exact moment of ovulation. So you may be off on when you think she is ovulating. In this case, having more sex could help. :-)
Good luck!
well before you are going to ovulate and or on your wifes more fertile day you want the sperm waiting for the egg , The length of sperm inside the female body really depends on the environment, or the cervical mucus being made and how strong the sperms are... The sperm carrying the female chromosome's live longer because they are stonger. Sperm will survive longer during a woman's fertile days where she is producing more cm. If you are dry when you have sex, the sperm may not even survive 24 hours. Outside of the body they don't even live for 5 minutes... they dry out, the need moisture, the CORRECT pH balance to survive longer much luck on your journey.....

Once ovulation occurs there is no other fertile time when she could conceive. It's only when ovulation takes place, after that it's just for fun ;)
