I just start taking birth control pill when can i stop using condom?

After 2 weeks...have fun!

I'd wait a month. Thats what i did
One month. Some will say less, but since there's little more margin for error with the Pill, allow one month.
Please keep in mind that the Pill doesn't protect at all against STDs. Since you're still using condoms now, it's a good idea for you and your partner to get tested BEFORE you have unprotected sex. That'll save you a LOT of grief later on, if someone ends up having something.
If you're not monogamous, sorry, but you should definitely keep using a condom. The Pill is an added assurance in case the condom doesn't work.
Give it at least a one month cycle on the pill before you stop other methods of birth control, or you WILL get pregnant. The pill takes that long to build up in your system and prevent conception.
You also need that long to see if you will have any side effects from the pill, and may want to stop taking it.
I was on the pill for 20 years
OK, first of all my dear, why would you want to stop using a condom? Birth control pills DOES NOT prevent STD鈥橲, and there is still a chance that you can become pregnant. Think about what it is you are wanting to do
The pill doesn't prevent STDs so I would continue to use condoms. For pregnancy prevention it is always best to use a backup method anyway. However the pills should be effective after finishing the first pack and having a period. Also if you don't take them correctly that increases your chance of becoming pregnant.
