I HAD TREE U/S MY FIRST ONE WAS MAY 18 AT 5WEEKS 5 DAY, 7WEEKS 6DAY AND 9WEEKS 5DAY THEY SAID IT LINE UP WITH MY LMP AND I CONCEIVE AROUND APRIL 22. THE THING THAT GOT ME KIND OF SCARE IS THAT I HEARD SPERM CAN LAST UP TO 7 DAYS AND IF THAT TRUE IS THERE ANYWAY PARTNER 1 CAN BE THE FATHER? AND WOULD THE U/S PICK UP IF THE BABY WAS BIGGER THAN 5WEEKS AND 5 DAYS AND IT WAS A EMPTY SAC AT 5 WEEKS. I AM BACK WITH PARTNER 2 HAD HAPPY I JUST DONT WANT THIS TO BREAK US APART AT THE END. DO YOU YHINK THERE ANYWAY I GOT PREGNANT FROM APRIL 12 WHILE MY PERIOD ON ? AND LAST QUESTION WOULD THE U/S PICK UP A WEEK BIGGER 6 WEEKS 5 DAYS THAN A 5 WEEKS 5 DAYS GA
AnswerI've already answered this for you, but I'll try to answer your questions again and hopefully put your mind at ease.
1) Sperm can live for 3-5 days in the fallopian tube. Very rarely up to 7 days (that is not the norm)
2) From the information you gave, Partner #1 is not the father. Even if the sperm lived for a week (highly unlikely, especially since you still had your period at the time and that environment was not conducive to sperm living for a long time)
3) Yes the u/s would have shown a lot more if you were really 6 weeks 5 days.
Is it theoretically possible that Partner #1 is the father - yes. I would say much less than 1%. It would require the sperm to have lived for a week (which is rare, and only under optimal conditions, which you did not have) and it would require that 3 first trimester ultrasounds were off by 3 days, which is the outer limit of how off they can be.
Also, you had sex with Partner #1 once, and you had sex with Partner #2 three times.
Based on the information that you gave, I would say that the odds that Partner #2 is the father is over 99%.
I hope that helps.
