Very Faint Line

Desiree
After feeling run down and just "feeling" pregnant - I took a test this morning. It's 6 days before my expected period and I saw it - the second line! It's very faint, but no denying it's there! 
This is my second pregnancy (first ended in miscarriage a few years ago) and while trying to not get too excited, I can't help it. My s/o and I are over the moon ❤️ 
The crazy thing is, I swore I knew the moment it happened. Has that happened to anyone else?
