I think i'm sick...

I went to bed last night at like 9:30 and fell asleep instantly...woke up this morn at 6'ish and was exhausted so i fell back to sleep until around 8'ish..still felt exhausted so i fell back to sleep again. When i woke up at 9:30 (I never sleep in this late) i had a headache and my neck hurt. I have felt off all day & feeling a little nauseous all day. I put a nice roast in the oven w/peppers and onions and sweet potatoes and the smell made me almost vomit. I ran to the bathroom and as quick as it came it went away. I now think the smell is delicious. It's too soon for symptoms right?? AF is due on Wed...i have been cramping off and on since O and i've had no cramps today. Just feel like shit. So wierd...must be getting a stomach bug. Ugh....dh is on his way to stewarts to get me some ginger ale. I hope that helps.
