Odds don't matter: The brief interval between exposures make the question too close to call. There are significant legal burdens when dealing with parental rights and responsibilities. This one will take paternity testing to sort out the issue. The NIPP, a non-invasive test on a maternal blood sample can be done as early as 8 weeks and provides court level determination of paternity. ...Read more

Depends: To properly answer that question we'd need to know which person you had sex with on which date. However, if you had sex on 4/22, then no, it's not possible to conceive on 5/2 to 5/10. Conception is within 2-3 days of sex, max. You may need to consult your doc to get paternity testing done if the true date of conception is in question. ...Read more
Can someone be the father of a child born at full term on july 5, 2012, if the conception date was november 5/6, 2011?
Numbers don't work: The numbers don't work for a full term newborn @ 7/5/12 if the supposed conception date was 11/5-6/11. That would suggest a pre term baby not one at full term. Dna studies are the standard in questioned cases & most maternity hospitals have the information on available testing labs. The complexity of the study makes it difficult to do at most hospitals. ...Read more

Likely the boyfriend: At this point to the bf as likely. The swimmers left by the ex were dead & gone the 14-18 days later you say you conceived.

Genetic testing may be needed to sort this out. ...Read moreSee 1 more doctor answer

(A simple way used over many centuries is: the father of the baby is the man she is married to.) ...Read more

How can a conception date be determined if it is possible to still conceive in the first 2 weeks of gestational age?
Why do some docs say that the accuracy of conception date determined by trans u/s depend if I have a reg 28 day cycle and some say that it doesnt?
Confusing-ask doctor: Conception does not necessarily occur on the same day you have sex, so the most accurate date is a known last period. A woman's cycles can be 21-35 days apart, and ovulation occurs on day 7-9 on shorter cycles, around day 14-16 for the "classic" 28 day cycle or day 18-21 for the longer cycle. Us dating assumes the average cycle, so a 7 week pregnancy would indicate conception about 5 weeks ago. ...Read more
