Just wondering how many calories and fat/carbs grams I should be eating? Need some suggestions please!!

Your nutritionist would be the best person to give you that advice. It is going to be different from person to person based on your weight, your goal weight, metabolism, general health etc. For example I am almost 5 months, my nutritionist wants 1100 kcals a day, no more than 40gm carbs. Hard to accomplish, but I do what I can. Some folks aren't past 800 at this point. So you probably will want to have that discussion with your nutritionist.
