Hi! I m pregnant. My last period was October 7th 2009. My doc says my due dates July 13th-15th. I had an ultra sound at 14wks an 18wks. They both gave me the same due date of July 13th-15th too.. My cycles are 31 days not average 28. (which is important when determining) I had sex with my husband everyday in October until we split. Then i slept with a friend on October 27th..One time. Based on this info whos most likely my babies father?
Hi, I have gone through your question, and I think I have understood your concern. I will suggest you the best possible treatment options. In a woman with regular cycles day 10 to 20 of the cycle is the most fertile period of cycle.  In your case it falls between 16 and 25 October.  Even if your November periods WE expected on 7 November, ovulation day, will be around 23 October.  I hope this information clears your doubt. Still you can get DNA paternity test, in case of any doubt after the birth of your baby. I hope this answer helps you. Thanks Chat Doctor.
