Faint line (Clearblue) and then Negative Digital Clearblue

I think I’m going mad!

I need advice!

I took a test Saturday (Always rest every month as I’m paranoid!!)

Got a faint faint line...

This morning, I took a digital ClearBlue with how many weeks and it says not pregnant.

I’ve been feeling really nauseous, boobs are not touchable without ache, and I keep feeling heavy, cramping only little bits and I just want to find out if that was a false positive or an actual positive..

What’s everyone else thinking?
