I can only imagine this. This is really gonna be very tough and challenging. We were 3 people there to take care of my wife when she was pregnant and still we felt helpless many a tines. I can only imagine how difficult it will be going through with it alone. You may seek some NGOs, or private institutions where they can help you thru your pregnancy journey. After birth, it's again gonna be even more difficult but atleast you'll have one companion with you, the true source of power. After birth, I believe you will make it your own.
You can always reach out to https://www.alife.org.sg as they provide counseling to pregnant ladies :) you don’t have to walk through it alone
