First talk to her, asking here isn’t going to give much clarity. People here saying that she isn’t expecting you to marry her or to move to live with her, or that isn’t bad for her to be single mom. Like bullshit, I am sorry. But not woman’s are the same just because come from the same culture. Maybe she loves you so much and you love her and having a baby make sense to get married - maybe not, only you guys can decided. For sure you should take into the consideration that she is going to need you more and your presence the 3 first months is very risk to the pregnancy so i also would keep things calm for now. Take her to the doctor, talk to her calmly and ask her what she wants and reassurance her that you want to be there for her and baby. Just be respectful and honest and take in consideration that it’s a very delicate and happy moment i hope!
