Very faint positive disappeared- possible pregnancy?

Hello!

Wanted your guys thoughts - obviously I will be retesting but wanted to see if anyone has had a similar experience and wanted to share their outcome. This is what happened:

Took a cheapie pregnancy test this morning (it would be super early) and initially there was a very faint positive but as the control line got darker, the positive line faded and ultimately disappeared within the alloted time window.

My question is - does that normally occur as the urine passes through the test or is it possible a tiny bit of hcg was detected but ultimately the control line was stealing the dye?

TIA!
