hmm. first of all i think u guys should sit down and talk nicely before u do anything..
talk to the girl nicely and decide whether both of you want the baby or not if she's really pregnant.. of course it will be better if u buy a pregnancy test kit to test it..

secondly, if let's say both of u agree that abortion is the best way already, then go ahead and consult the gynae. the earlier the better because after the first trimester, to do an abortion is very dangerous to the mother and it is quite costly as well compared to the abortion during the first two months..

so decide wisely and dun let yourself regret
