OK in December I had MY cycle came on THE 9 AND on THE 13 AND 14 I had sex with a ex then on December 21 TO December 30 I had sex with MY boyfriend MY due date IS September 20 who IS MY baby daddy

The dates are too close together to even give a guess. The only way to determine paternity in this case is with a DNA test after the baby is born. Due dates are an estimate, even with an ultrasound. They can be off up to 2 weeks either way (a month). Since you had sex with two different men 9 days apart, you won't find out who the father is via a due date.

Good luck.

But how if I didn't have sex with the ex on the 15 16 17 18 19 20i don't get it at all I count back 38 week from my due date and it came back December 28

Thanks but I DON'T believe that THE ex IS THE father because
Cause I count back in it's NOT adding up

That's great then, you know the answer and were able to answer your own question. Bravo.

Truth be told, Alty is right and everything is just an estimate. You need a DNA test once the baby is born to be sure...

But then, you know the answer anyway... and it makes me wonder why you even asked. I guess you just wanted people to tell you what you wanted to hear.

You don't believe because you don't want it to be, that doesn't change the fact that it's possible.

Your due date is an estimate. Do you know what an estimate is? It means that it's not set in stone. A due date is a best guess, it can be off 2 weeks either way, early or late. Add 2 weeks by another 2 weeks and that's a month. You have a 9 day discrepancy between partners. No matter how much you try to tweak the math, 9 days is well within the parameters of it being either mans child.

You can guess all you want, you didn't ask for a guess, which is good, because there's no way to guess. The only real way you'll find out who the father is, is a DNA test. You don't have to like the answer, but those are the facts. If you want someone to lie to you, talk to your friends. On this site we post the facts.
