nervous to test

Kristyn • 35 with PCOS and TTC my first since 2008. Miscarriges 4/14 & 7/15 hoping for a rainbow baby .
I know I should test cuz I can tell my pegesterone is low but I'm getting many of the same symptoms as my pregnancy in July. I need to test so I can get on pegesterone asap! ... but I'm scared it's all in my head :(
