Women's Health :: Fatigue, Feeling Faint And Cramping

I've been seeing my doc lately about some extreme fatigue I've been having. I've had issues with fatigue for a few years now, but about 6 months ago it has gotten to the point where I could hardly make it to school as I have fallen asleep at the wheel for a split second. So my doctor put me on Prozac because of my history of depression. I tried it for the 8 weeks to no avail, and at this point I doubt it is depression. I've been there before, and I have been doing fine. I'm young and very motivated. Since I've been off of Prozac, my fatigue has only gotten worse. I initially thought it was just because I was getting off of the meds, but about a month later, I continue to feel worse. To the point I can hardly function at my job anymore, let alone get anything else done. I then had my Thyroids tested only to be told they look fine

Then I start to notice that I have been feeling faint a lot lately. Mostly when I make sharper turns, but at times it can come on out of nowhere, like when I'm sitting still! The only thing that really helps this is to lay down until it goes away, and sometimes it will not so I'm forced to go to bed early.

On top of this my periods have been rather irregular. They always have been a little irregular, so sometimes I will miss a period entirely, but mostly I will just have a longer wait until my next period. Lately, they have been coming early. Generally they will be 6 weeks apart, but then I had one that was 4 weeks apart.But everything seemed normal so I brushed it off since I'm used to being irregular anyways. But then my last period started just barely 2 weeks after my last one began! It was a lot lighter (and the blood was a bit thinner) and lasted a couple days less than normal which would be 6-7 days. I also haven't had sex in about 3 months or so.

Along with this I started to notice some muscle soreness and the occasional headache. At first the soreness was random and all over my body, then about a week ago, it all seemed to be in my lower back and lower legs/feet. Now, in the past several days, I've been having severe cramping just like menstrual cramping along with the lower back and leg/feet pain. I'm not due for another period anytime soon, in fact, I just ended my "period" not even a week ago. I've never had cramping in between periods, never this bad, and never for this long.

I am in the process of setting up a sleep study, and I scheduled another doc appointment for June 23rd to discuss my more recent symptoms, but I wanted to know if anyone might have an idea as to what this could be, or if I should try and see someone sooner?
