Newbie needs opinions!

Hi all! I just posted a picture of a FRER a little while ago. 
I am currently estimated about 12dpo. 
10dpomorning, I took a blue dye test (two line test, not plus) and didn't think I could see anything. I put it into my undie drawer to check later, my husband was almost home from work, I want to surprise him if I am pregnant, so I was trying to be sneaky! 
I got home from work that evening and there was a very clear blue line on the test. I know that can for sure be an Evap, and that blue tests are known for that. However, I didn't look at the test that morning for anymore than 5 minutes or so. (I did the water test where you rinse it to see if the dye moves, it did not--don't know how accurate this is, lol!)
10dpo night, I ran to CVS with my best friend. Got the new FRER's. I took the test at 10:30pm, 3 minutes were up, she said "I don't see anything..." Handed me the test, and I said yes! Look right there! I could very clearly see a faint, faint pink line. Once I showed her where to look, she also saw it. The line was faint, but definitely visible!
11dpo, next morning, at 5:30am, I took another test. It looked identical to the one from the night before. 
I started reading reviews about bad indents on these, and don't know what to think. I have definitely had pregnancy symptoms, but don't want to get my hopes up! I was completely convinced I was pregnant until reading reviews on the new FRER tests. 
My period is due on Saturday. Not sure what to do from here. Help?!
