I think what you're talking about is the morning after pill but that can only be taken up to 72 hours after intercourse. If it is taken after that time span then it does not have any effect. If you're already pregnant then you're options are termination, adoption, keeping the baby..... There are people and helplines who will go through your options with you. It doesn't say what country or state you live in so I can't give you specific information of people to talk to. I hope this helped you're post was a little difficult to understand.
if you dont want to be pregnant, you should have thought to use some form of birth control. you might just be late and not pregnant. and i have NO idea what your first sentence says "now i am having 9months kid..." what did you just lik e have a baby or something because if so...then its normal for you to miss a period afterwards
