Im so sad right now

I have been having some really bad insomnia for the past two or so weeks (stress) I have been getting up multiple times a night so that had made temping a real nightmare, not to mention man have a I had to pee almost constantly which is waking me up! I can ususally get to about 6 am before I go but lately I have to REALLY go every 3- 4 hours at night that is not helping the really trying hard to sleep thing. Anyway this am as I got up to pee again about three hours after the last time I decided I would temp then because I knew I would not be able to go back to sleep. Well My temp took a big dive this am! I am trying not to correct the temps too much because I really want to see what my body does so I can understand my temps more, but Im affraid all the insomia its making things really unriliable.
I have been having things go on with my body this month that I am trying hard not to read to much into cause the last time I did I was totally let down when the

showed but I just cant help it.
Take a look at my chart and tell me what you think. I swear last month when I started this temp thing, it dove the day I started AF but Im not due to get her visit until Monday. So Im not sure what the factor is.
