I feel like I am going crazy!!!

LILO • We have three beautiful girls 14,12,11. Twin angel babies '09 and hoping for the best! TTC again this time since June '17.
Every twinge every headache cramp and odd thing I swear I am pregnant then I remember I am only 4/5 dpo... I am driving myself utterly insane!! I cant even test for another 6 days!!! How much do you want to bet I test before that and then get disappointed because it will read bfn. I wish I was off the next 7 days so I could just jump into a book and take my mind off this!
