How I understand my wife is pregnant?

My wife tell me that doing live togather 14-15 days then she pregnant. Actually I don't understand that. I know that 1 day live togather result is pregnant. But she not agree with me. And she not agree to use any Condom from 1st day live togather.

I don't want any baby with in 2-3 years.
So, what should I do?

First thing you do is you learn English, because what you posted is a bunch of jibberish. I'll try to answer it as best I can though, but I don't entirely understand the situation.

Okay, first of all, it doesn't matter how long you've been living together, it doesn't matter how many times you've engaged in intercourse, if you were to do it just once, without even living together, you could get a girl pregnant. Second, it takes 9 months to give birth, not 2 to 3 years. Third, if you don't want kids, you shouldn't be convincing her to not use a condom, but encouraging its use instead. Fourth, if you don't feel ready, ask her to get an abortion, but keep in mind, you need her to agree to it too.

ok tell her u didnt wanna have one and mabey put it up for adoption

First thing is BE A MAN. If you don't want a baby then don't have sex without condom.
Now that your wife is pregnant, I repeat, BE A MAN, take care of your wife and
and your new baby.
That baby is your future and your legacy. Be there for your wife and your baby.

When your baby is older he will take care of you when you are old so be good to him.
Don't ask your wife to kill the baby, BE A MAN.

Sorry but I agree with Oni; can't understand what you mean. Are you trying to say that you don't believe you're the baby's father or that the pregnacy just doesn't fit your time schedule? The answers would be considerably different.

Why don't you have someone with English skills re-submit the question?
