I think you need to take things step by step. This calling kutta, kutti, billi, bandar etc is not as important as your health and the baby’s for now. Firstly, how far along are u, i believe…first trimester according to your symptoms. This cigarette smoke all around you is extremely dangerous for your babys health. Are you going for your regular checkups to your ob/gyn and are you taking any multi vitamins? Are there any women/infant charity programs that help out low income families that provide food stamps you could sign up for and get free groceries? If you are going in for regular checkups to your ob/gyn, discuss this with him/her and maybe she might be able to guide you where to get food stamps and all. You need to make your diet top priority over everything and try to stay away from all that smoke, perhaps move in with your parents for now or ask your mom/sister to help you out somehow. I dont want to scare you but babys first 3 months of development are the most vital when all organ systems are forming and start functioning and you need to take very good care of yourself specially at this time.
