Hello, how much weight have you lost from contraception? Eat well, too. It's not good for your health, which will lead to malnutrition. You can have a baby, you can lose weight, you can eat more fruits and other foods when you are pregnant, and your mood will be better. I don't recommend not eating before. Personally, I think so. I hope I can help you. I wish you happiness every day and get pregnant at an early date.
