Sounds like she got pregnant from the sex on March 10. If the only time she slept with someone else anywhere near then was the time February 24, you're the dad.
If her first ultrasound was at 5 weeks, it will be the most reliable for working out a conception date. Here is how the due date of December 1 works out on a conception calculator:
Probable date of ovulation: March 10
Possible dates of conception: March 6 to 14
Due date: December 1 (40 weeks)
Here is how the due date of December 4 works out on a conception calculator:
Probable date of ovulation: March 13
Possible dates of conception: March 9 to 17
Due date: December 4 (40 weeks)
Neither of them implicate the sex on the 24th of February.
In case you are wondering how someone can be told they are five weeks "pregnant" when they didn't conceive five weeks prior but only three weeks prior, it is because doctors count pregnancy from the first day of the last period, not from presumed conception.
Good luck, sounds like that week of the 10th was the hot week. Your sperm from the first event could have even still been viable by the time you had sex again, it's said to live in the woman's reproductive tract 5, 6 or even 7 days, though to be most viable before the 6th day.
And yes, count the spotting after she went off the pill, as a period.
no she had sex with the other guy the 24th
so u saying the sperm from the other guy on the 24th could've got her pregnant??
To repeat:
Sounds like she got pregnant from the sex on March 10. If the only time she slept with someone else anywhere near then was the time February 24, you're the dad.
His sperm would have been long, long dead and gone out of her system after 14 days or more.
If her first ultrasound was at 5 weeks, it will be the most reliable for working out a conception date. Here is how the due date of December 1 works out on a conception calculator:
Probable date of ovulation: March 10
Possible dates of conception: March 6 to 14
Here is how the due date of December 4 works out on a conception calculator:
Probable date of ovulation: March 13
Possible dates of conception: March 9 to 17
Neither of them implicate the sex on the 24th of February in the slightest.
Also, on the 24th of February, she had no egg. A woman's eggs only live 24 to 36 hours. She is not sitting there with ready eggs every day of the month.
ok i was just confused because u said she got have gotten pregnant from the first event
I don't think I said that, but it's hard for me to know which event is "the first event," you have named a lot of events.
I think you said "then on march 10th in 17th we had sex" and took that to mean then on March 10th you and she had sex, and then on March 17 we had sex." If you're saying something else, I'd want to know.
Point is, I said several times that the sex on February 24 has nothing to do with anything. Sperm just does not last that long.
