Feeling a bit crazy

So I see people all the time online who in their desperation to become pregnant post things like "my big toe hurts, am I pregnant?" and even though some of the questions seem off the wall and illogical, I understand that wanting something so bad especially when you are going through fertility treatments can make even the most logical person go a bit nutty. I'm feeling very much so in the nutty boat right now. In my heart I know that I am not pregnant, even though I want so desperately to be, but my body is currently going crazy so it's hard to shut off that little voice in the back of my head telling me again and again "take one last test". While I know that the fertility drugs can give you pregnancy symptoms until it is out of your system, I really feel like my body is playing mean-hearted tricks on me. The Ovidrel tested out of my system on Day 4PO, my sore breasts continued though until about day 9. On day 6 I awoke in the middle of the night to horrible pain on my right side through my bottom (which was also the side I ovulated on). The ER doc said that it was either an Ovarian Cyst that burst or bad gas, but nothing was definitive. My PCP ran an upper abdominal ultrasound to check out my gallbladder etc and everything checked out fine. When AF "came to town", the entire 3 days consisted of light to dark brown blood with dark flakes in the toliet after urination (sorry TMI). Now a week after AF I'm still having occassional lower abdominal cramping, my legs are sore, I am utterly exhausted to the point that I'm taking a nap nearly every day and I'm peeing like crazy. I took another test this morning, the big "Not Pregnant" popped up pretty quickly. While I know that there is likely something else going on with my body, I can't shut off that illogical part of my brain... and it's driving me crazy.
