Here is my question. I had sexual intercourse with a girl on June 28th, I wore a condom, and afterwards I even checked the condom to make sure there were no leaks by filling it up with water, which there were none... (faulty condoms have always scared me, that's why I checked it)... well three months later I find out she's pregnant and due February the 29th. In the beginning she said it had to be mine, then she said that it wasn't mine and that it was some guy she dated before me, and now she's saying its mine again, and I don't want to go through that feeling again unless it's a possibility.. So, we had sex the 28th of June, with a condom, and she's due February the 29th? Is it mine?

Have a blood or DNA test done. That way you will know for sure.

Soory, but you will need to wait until the baby is born, then request a paternity test.

I know about waiting to get the DNA test, which I will do, but I want to know the possibility of it being mine, cause I've been walking around like a zombie for the last 2 days... so I'm not asking if its guaranteed mine or not, just what's the possibility of it being mine...

If you had sex with her then the chance is there.

All the conception calculators (I have done 4 online), say the conception date would have had to been earlier than June 28th.
Did you have sex with her anytime prior to the 28th?
Was that the ONLY time you had sex with her?

Now, while these things say it is unlikely you are the father... it most definitely does NOT rule you out.
So, while I would say you are most likely not father, the only way you are going to know 100% is by a DNA test once the baby is born.

i know about waiting to get the DNA test, which i will do, but i want to know the possibility of it being mine, cause ive been walking around like a zombie for the last 2 days... so im not asking if its gaurenteed mine or not, just whats the possibility of it being mine...

You had sex with her, therefore the possibility exists.

You should definitely do a DNA test. I know that it takes a long time and you probably don't want to wait that long. Plus, if you wait... and don't buy anything for the baby or do anything to prepare for it, and it turns out you ARE the father, you are going to be completely unprepared and very overwhelmed with it all. I also checked a conception calendar online and if she is due February 29th, then (by this calendar) she would have conceived around June 8th, so there is a 20 day difference, but as "macksmom" said... this does NOT rule you out.

Hope this helps... try Pregnancy Date Calculator (http://healthlink.mcw.edu/article/923526833.html) it is the conception calendar I used for this...

I hope for your sake you aren't - you sound responsible and this girl sounds like a real piece of work!

The dates don't quite add up so my feeling is that you might not be. But really who can even believe when she's due! She sounds like a liar!

Best of luck mate!

Thanks for everyone's responses... Yes I know there is a possibility, anythings possible, I'm just trying to find out anything I can... And nothing adds up, I used protection which didn't bust, and I know condoms aren't full proof... but its one of these deals where I don't think she really knows who the father is... but if its mine then I will be the father, a good one, there's no question about that, but I just don't see how it can be mine, but anyway, thanks for everyone's input...

I think you may want a DNA done I am pregnant and due Feb 13 which made me conceive in mid May if you had sex on June 28 that's a little off.
Good luck though

Due 2/29 (http://healthlink.mcw.edu/article/923526833.html)

Its possible because due dates are an inexact science - there is always room for error. There is a chance its not yours though. It'll feel like a long wait but DNA is the only way.
