India, sex / pregnancy before marriage is this bad?

Ive been dating an Indian and the stories I hear on social media and through people it scares me especially what they say about the Indian religion or culture. I love him, I truly do and I don't want to lose him, his parents know about me and apparently they're fine about us. But the question I ask myself is it okay to have children before marriage because this is something him and I are planning on doing and he's given hints about it to his mother which she sounds like shes okay about it but to be honest I have no idea if it would affect his Family and put shame and guilt upon us, im scared that something bad would happen to him or I, I don't speak the language but he's helping me learn and that's something I feel I have to do is learn about the culture and language first, him choosing me from a foreign country is a really big life changing decision. I truly love him and he is gonna be the first and last love of my life.
