Actually me and my wife do not want a baby now as we are working and our life is not settled but we had a sexual interaction then she took T-pill 72 then after 3 days we again had a sexual interaction so I just want to ask that can she take T-Pill 72 again to stop the pregnancy or there is any another way to stop the pregnancy now as we do not want a baby now

Then stop having sex. What other birth control is she on, she needs to see her doctor and get on regular birth control pills, and then you should use a condom in addition.

The "morning after" pill is not designed for regular use but emergency use for non planned sex.

You both need to sit through Classes on human reproduction... its obvious neither of you have a clue how babies or made or you wouldn't have this problem.

OK... but I just want to know where this pill will work for now or not... I will be using the condomn now on... but I just want to know that how to protect the pregnancy as for now

Yes, if it was in the last couple of days, she can take the pill again, but as was said, it is not meant to be used as regular birth control. Too high of a concentration of the hormones that are in regular birth control pills.

Keep in mind that even the emergency contraceptives are not 100% effective... so there will always be a slight chance of pregnancy, with any form of birth control. Since you are wanting to make very sure that a pregnancy does not occur, either stop having sex (which is not likely to happen!) or use two forms of birth control... regular birth control pills (or something else) for her and condoms for you.
