What’s going on 😩

Faint positive at 8DPO (I know really early to test etc etc) but I was within the time frame for FRER as my period is due at 13DPO.

I tested today at 10DPO and got a big fat negative.

Why is this 😩😩😩😩😩 I am convinced I’m pregnant but why would it go from faint positive to nothing at all 😭
