Should I tell my parents?

I am 22 years old, living with my fiancé, working a full time job and ready to ttc. I have been with my fiancé for about 4 years and my parents didn’t know about him since August of 2019. The reason I didn’t tell them about him from the beginning is because I was afraid they’d threaten me to leave him since he‘s a different race and my parents are very traditional. (Parents are Indian) Long story short.. First my parents told me to choose between him or them, then they said they’d get me married right away and now it’s been months... and they still haven’t met him.

My brother went to India for a month, and a few days before his flight home.. he decided he wanted to get married to a girl he saw at a wedding... so now they’re “engaged” and won’t have their wedding until feb 2021. Btw my brother has disowned me ... he is not talking to me. My parents are expecting me to go to the wedding because if I don’t ppl will be asking questions but I don’t know if I want to go.

I’ve always wanted to have a baby and I want to ttc but if I do become pregnant before his wedding... should I tell them I’m pregnant?

They’d be very upset and idk if I should put the stress on myself and them...

what do you guys think?
