Pregnancy test question

Ashley

To start, I know you're only supposed to read a test result in the designated time frame, I just noticed this and thought I'd ask!

I'm a week late and after taking several tests this week (all BFNs) I was taking out the garbage. I noticed that one of the tests (different brand from the rest) now has a thin pink line in the test area.

Obviously not getting my hopes up but since this is the first time it's happened (I've seen grey before but never pink) I did some digging and read that the line will only show colour if HCG was detected.

I was just wondering if anyone else has had experience in this or had thoughts.
