Very, very faint line on Clearblue pregnancy test...

Hi guys, I'm about 2 weeks late on CD52.

Did a pregnancy test on the 15th of March, as I believed I was having pregnancy symptoms, which to mine and DHs despair came out negative. I decided to do another test earlier as AF has still not shown up. This is the result from the test I took today but the line is so, so, so faint that it is just barely visible! Is this a positive or negative result? 😭

Husband and I have been trying to conceive for exactly 1 year so this would be our dream finally coming true if it is a BFP!!!

The uncertainty of this result is driving me insane so I would really appreciate your opinions or if anyone has also experienced this. 😊
