So I've been urinating a lot more then usual. I've had cramps but as severe as they are when getting aunt flo. I've got a constant headache from the time I wake up. I feel so tired all the time no energy at all. I'm always craving sour things and got a metallic taste that changes the taste of food which doesn't taste to good lol. i sometime feel sick but I try not to get sick. I've been emotional like crazy. My period isn't due until Tuesday the 18th. Is it to early to test or should I wait until I'm expecting my period. I've had a miscarriage in Sept 2011 so I kind of don't want to get all excited.
