I haven't had a period since 12-23-10, so I am LATTTTEEEEE. I feel awful, I feel pregnant for one. My lower back hurts all the time, I'm tired all the time, I've never really puked but I've get close so many times through out each day and my stomach hurts alot, when I eat I'm NEVER full anymore, I'm peeing alot, and sex suddenly feels A LOT better. I do not take birth control, drink or do drugs. I'm usually regular, I'd miss maybe one period here and there but I've never missed two. Soon to be three. :/ Anybody have any idea whats going on?
