Hey guys! Help needed!

So I tested yesterday (8DPO) and got a faint positive on FRER, it got darker when it dried outside the testing window.

This morning (9DPO) I got another faint positive on FRER, but when it dried the line went away. Does that mean anything?

I realize it’s outside the testing window when it’s dry and I’m trying to not let it confuse/upset me but I was wondering if anyone else had this experience and ended up having a successful pregnancy?

Thanks!
