The best advice that I can give is to get back to your eating plan, and see about getting some pregnancy vitamins, because it is vital that you keep your strength up, esp if you've miscarried before. ( I have too, but there is no sense in focusing on that.) Just keep focusing on the positive side; you are having very real symptoms that will pass soon enough, and if you could maybe get a good friend or famliy member in to help with the cooking/cleaning, then you will feel less stressed, and more like eating healthily. Always remember that the mood swings are are definite sign of healthy raging hormones, and try to keep things in perspective..and remember to laugh at things afterwards, even if they don't seem funny at the time. Bananas are so good for mood swings, full of potassium, and other good stuff, and no preparation needed. Good luck!
