can someone help me figure this out?

[mommyofbeautifulgirls]

I have a question.. a girl is saying she is pregnant by my babys dad she says that they had sex on New Years & that she got pregnant at that time but her due date is September 12th I'm a little confused because my cousins girlfriend is just the day before that girls (September 11th) & she concieved mid December so how can she have concieved at a different time but still have almost the same due date.. I looked on a lot of due date calculator's, trying both December 31st 2013 & January 1st & it gives me the date of September 23rd or 24th & a friend of mine conceived on the first week of January & had her baby in the first week of October, I have a feeling the girl is lying that it's my babys dad I also looked on the conceived calculators & they all said mid December the same as my cousins girlfriend, can the baby be my babys dads? Calculations aren't making any sense

Wow I conceived in December 23, and my due date is then21 of September! Get a DNA test I have been down this road and my husband never touched the girl lol... He told her he loves his kids and wife more and hopes her lesson is learned!!

I seen that you left a comment saying that your due date was sep 20 and you got pregnant around the 19. I have a question, my due date is also sep 20 and the apps are saying I conceived dec 28. I'm in a sticky situation because I had intercourse with my bf dec 25 and on the dec 28th at 5:00am so basically the 29th with and get then on jan 1 with my bf again. I'm having trouble figuring how who the father is. I'm pretty sure when my ex and I had intercourse he pulled out but I'm not 100% sure all the way and now that my due date is getting closer I'm getting worried

Her baby could be measuring big and the dr may have changed her due date...I conceived on New Years and my due date is sept 15 but my first due date was sept 23

Don't start counting 40 weeks from the date of conception you start counting 40 weeks from the last menstrual cycle.  
  Results:  
First Day of Last Menstrual Period:  December 6, 2013
Probable Date of Ovulation:  December 20, 2013
Possible Dates of Conception:  December 16 to December 24, 2013
Due Date:  September 12, 2014 (40 weeks)

Remember these calculators are based on a normal 28 day cycle.  Sperm can live for 1-2 days after sex as well.  I know we had sex Nye and my due date is 9-25.  Conception date is 1-2.  Id say prob not his but only dna can tell. She may ovulate differently.

If she got pregnant on new years day and you start counting 40 weeks from that day her due date should be around October 8th no where near September 12th

I conceived  on December 23 and I'm due on sep 15

So it can't be his baby?
My babys dad says that no he was not with her.. she says she had sex with him on New Year's & is due September 12th but the calculations don't add up to September 12 if she did got pregnant on New Years

[bethany092914]

Im due September 20 th and I got pregnant around December 19th sounds to me like she lying about who the father is

[mommyofbeautifulgirls]

Yeah because I've gone on sooooo many DIFFERENT sites of due date calculator's & they all say the same thing

I have a feeling she is lying but the only way to really find out is a DNA test x but the calculators on these sites are pretty accurate xx
