conception due date

[dijon405]

have a question i was wondering if anybody could help

ok me in my kids mother i have twins.. were broken up in she was sleeping around in she ends up getting pregnant so heres the scenario

her very first period was from feb 1 to the 5th of feb
she started taking birth control on the 4th we had sex on the 14 of feb

then she had sex with him on the 24th of feb.. then she spotted the 26 to the fist of march she stopped taking birth control march 4

she txtd me on the 8th of march saying she had clear stretch odorless discharge when she wiped ( I'm thinking ovulation )

then on march 10th in 17th  we had sex .. she found out she was pregnant march 26

on april 2nd she had a ultrasound in there was just a sac no baby she was ges  5 weeks 0 days

so her doctor said she just had gotten pregnant so if she was 5 weeks in she conceived 3 weeks ago 3 weeks from april the 2nd is march 12th

so ges 5 weeks technically means her last period was feb 26 right??

just give me your thoughts i look forward to hearing from someone

ps she took pregnancy test 2nd 3rd 4th 6th in the 8th and 18th of march in they were all negative

oh i forgot to add due dates at her first ultrasound april second the sac measured dec 1 then when she went back it changed to december 4th in it has stayed ever since

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.

ok i was just confused because u said she got have gotten pregnant from the first event

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.

so u saying the sperm from the other guy on the 24th could've got her pregnant??

[dijon405]

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.
