The conception calculator I use suggests March 27 for the estimated date of conception if the due date given to you in a seventh-week ultrasound was December 18. But with the dates of sex with the two guys only 4 days apart, if your ultrasound was later than your 8th week, the margin for error would soon expand to include both guys.
Im assuming i wouldve been between 6 & 8 weeks. He didnt tell me a precise week because i couldnt remember when my last period had began in march.
Honey, I can't help you if I can't tell from what you are saying just how early you got the information that you had a due date of December 18, and most especially, if that information came from an ultrasound.
If your info came from an ultrasound but the ultrasound was after your 12th week of pregnancy, it can't be used to pinpoint when conception was no matter what the doctor said about the date of conception. If he said you conceived on a certain date because he was looking right at your 7th week ultrasound, then that's a useful estimate. If he said it when he was holding your 19th-week ultrasound in his hand, it's not that useful of an estimate. Some babies grow slower and some grow faster. Only the earlier ultrasounds are useful for trying to determine when they began life.
Im not sure. I was admitted into the ER & thats how i found out i was pg. The dr said placing date of conception on march 24th according to ultrasound but i didnt have sex then. It was 3 almost 4 days later & he pulled out. I then had sex 4 days after the 27th. Which lands on april 1st & he ejaculated inside .
So, that was, what? In your eighth week or so? And it was the first one that gave you the due date of December 18?
I had my first ultrasound may 5th.
Honey, I was asking at what point in your pregnancy you got the ultrasound that said when you were due. If your ultrasound wasn't early in the pregnancy, it can't totally be relied on to identify your due date (or your conception date), because as the pregnancy progresses, ultrasounds get less accurate for trying to tell when you conceived. How far along in the pregnancy were you when you had an ultrasound that said you were due December 18?
This is what I got if I input your due date into the conception calculator but this is only if due date is correct keep in mind ultrasounds can be off .

Im sorry I ment cycle length as in every 28 days you get your period or how long is your usually cycle length if you keep track.
My last period was march 13 i have a cycle length of 29-31 days they told me based on ultrasound my ovualtion date was 29/30th of march with that due date given december 20 based of ultrasound .
How did you get the 27th as your peak ovulation?
The ultrasound said december 18th. But that would mean i got pregnant on the 24th & i didnt have sex that week until the 27th.
Was the ultrasound that gave you the due date pretty late in the pregnancy?
My cycle length is pretty long. About a week or so
My last period was march 15th. The second man finished. My due date is december 26th
Did the second man use the pullout method too? Or did he finish?
When was your last period? Usually cycle length?
Earliest ultrasound given due date ?
Could go either way since the days were so close together. Only way to know would be a dna test. The pull out method is not an effective form of birth control because of pre ***. Many women have gotten pregnant using that method.
