Faint lines and a negative digital

Okay, I just posted about having a positive test and a negative one. I took two regular test and one digital. The two regular test shows a very faint line but you can see it! And the digital was negative. My fiancée and I have been trying so hard and really are so excited and happy. But we are not trying to get our hopes up. My period is suppose to start in 5 days.

When do I take the digital one ?? I know my hormones have to build up.

Also have you ever heard about a test bleeding over for a false positive ? My friend was telling me this might be the case.

I just need some advice before I get too excited. Thank you ladies ♥️♥️
