Bfp 10 dpo and bfn 14 dpo

Hi

Last Friday I got a BFP with CB (blue tint) and CB digital. I was 10 dpo.

AF is due today and I have a very regular 28 days cycle. No AF cramps at all.

I've been testing through the days and the lines are lighter.

Today I tested with first morning urine and got a faint positive. By the afternoon (after holding my pee for almost 3 hours and no liquid) I did another CB digital and got a "not pregnant".

I want to think positive but it's so hard... just need to open my heart.

*****UPDATE****** 7/aug

It was a chemical 😞 I woke up today having a super strong AF pain, seemed to be like contractions, for 10 minutes and then my period came...
