Now to answer the original question. Keep the baby. Find the guy. Get a paternity test done. Take him to court if anything. Get the parents involved. As shameful & embarrassing the conversation might be get them married if possible.
2nd option Keep the baby. Still find the guy. Paternity test. Court if necessary to make him pay child support & wait till you find another understanding guy who is willing to accept your "mistake" & marry you.
Either way aborting is a big no no.
I live in london in an area heavily populated with desis and if something like this happened the parents would never get involved esp with the whole taking to court thing and getting DNA test done as that just implies that she's been sleeping around with other guys which in a way adds even more shame.
I know of one situation where they actually kept the girl locked in the house for the whole duration of the pregnancy from when she started showing. They only sneaked her out for hospital appointments. The parents informed social services and told them that the baby is not wanted. They took her to hospital once she was in labour and the baby was taken into care promptly after birth. They only did this because she was too far gone when they found out. Had they found out before they would have arranged for an abortion.
The same thing happened in a 2nd situation. The parents found out but it was too late for them to arrange an abortion. They shipped the girl off to Pakistan and then moved out of the area. I have no idea about what happened to the girl or the baby.
Abortion is the worst thing possible but to some people they would rather have the gunnah of that than to 'die of shame' in the community.
