I got an ultrasound and I was about 16 weeks and 4 days pregnant which made my LMP of being december 5th and my conception date december 19th.They did tell me that it could only be off by 3 days. I was with guy 1 on the 19th and the 23rd of dec. I was with guy 2 on January 9th/10th. How possible is it for guy 2 be the father? Please help!
16 weeks 4 days is pretty far along in pregnancy to give you such pinpoint precision as to be off by only three days. That said, I've never read that it could be a three-week margin for error, and that is what it would have to be to get Mister January 9 into the picture.
Here is what the conception calculator gives you for the dates they said:
First day of last menstrual period: December 5
Probable date of ovulation: December 19
Possible dates of conception: December 15 to 23
Due date: September 11, 2014 (40 weeks)
There isn't any chance that the guy on January 9 is the dad.
