how far apart in between 2 partners should you wait to have sex in order to know exactly who the father is if you end up pregnant?

Mutual monogamy: What a "strange' but meaningful concept when engaged in sexual matters. It actually eliminates the need to "guess" which partner provided the necessary sperm to the event. You might want to give it a try so that the birth certificate will reflect the correct father.
Dr. Charles Whiting
Obstetrics and Gynecology 27 years experience
3 weeks...: Conception is dated by different methods and the accuracy can vary between +/- 5 days to +/- 3 weeks. If you wanted to be absolutely sure, you should wait at least 3 weeks. This is a risky game. It would be better to use contraception until you and your partner are both ready to be parents. Best wishes!
