I am freaking out! Is this real!?

We have been TTC for about 3 months. My period was due today. Been cramping for 4-5 days, expecting my period. Usually when I start cramping I start bleeding within 24 hours. Not this time. Found it a little peculiar. My period isn't even late yet.

I decided to take a test for the heck of it. Breasts are abnormally large for me and nipples are sensitive. I've noticed these being part of my regular PMS symptoms without my birth control.

Well...

Have any of you gotten a false positive with Clearblue Digital tests? I am in disbelief. Total disbelief. Totally excited, but I can't believe it!
