17 DPO and only getting faint line

Hi all,

I’m 3 days late for my period (it was due on Tuesday) and no sign of it coming.

I’ve been testing over the last 5 days and only getting faint 2nd lines on FRER.

The lines have been getting ever so slightly clearer but nothing significant.

A clear blue digital test is saying not pregnant. But it’s clear that I’m getting a 2nd line on the FRER tests.

I’m technically 17 DPO (I know this as took clear blue ovulation tests).

My bbt has been higher than normal for the last week, and no dip to suggest that my period is on its way.

I have had a few spells of nausea and dizziness, and a bit of mild cramping.

Is there still a chance I could get my BFP or should I be concerned that I am not getting darker lines at 17 DPO?

This is my most recent test I did this morning.

What are your thoughts? Thanks in advance x
