Wasted my FRER

Aislin
After getting a couple of 'is that a line?' Lines on the cheap pregnancy tests (early Evaps or indents) I decided to bite the bullet this morning and use my last remaining FRER from December.
Negative. And I got my first period post-miscarriage an hour later. Seriously, it couldn't have showed up an hour earlier to stop me wasting my money? 
Even better, because I started today it means I'm next due on on Valentine's Day. Grr.
