The spotting is not unusual in the first 2 months. If it happens in the 3rd month, get it checked out with your Dr.

For the fatigue: eat 5-10 MORE veggie carbs for a day or so. You might need them. And use some "No Salt" on your food. It's in the grocery store with the salt, but it's potassium. Since the diet is diuretic (makes you lose water), you could be a bit low on potassium. I hope you'll soon feel better - and be lighter.
