First, if all haven't already, make sure you're actually pregnant. I can't tell you how many women come on here assuming they're pregnant before they've even taken a test. So if you havent yet, take a pregnancy test.then, you need to tell your parents. I'm sure it will be hard, but they need to know. They will be the ones helping you through all of this. After that, you need to see a doctor or midwife for prenatal care. You need to start taking prenatal vitamins, a DHA supplement (900mg a day is the newest recommendation), and extra calcium. you can also just take a regular multivitamin (I like the gummies) and then also take a folic acid supplement.as far as your diet goes, eat lots of fresh fruits and vegetables, lean meats, low fat dairy, and whole grains. Drink lots of water. Avoid junk food and fast food as much as you can. I've found that the healthier I eat, the less I have cravings for sweets and junk food.
