6 days late, 17 dpo?, BFN

Question

Hello all! 
According to glow, my cycles have ranged from 27 days to 34 days in 2021. 
Glow calculated my period to arrive on the 19th - it did not. 
I thought I may have had a longer cycle (34) and waited until the 22nd - AF still didn’t show. 
I’ve taken tests in the morning/evening since then and they have all been BFN. 
Symptoms:
Light cramping off and on 
Headaches 
Nausea/acid reflux
Tired/exhausted almost all the time 
Emotional! 
I haven’t had any spotting that I’ve noticed. No sign of AF at all and I can’t recall ever having a period this late before. We weren’t actively trying this time so I don’t think I stressed myself out. 
In 2016 I tested positive at 19 dpo with twins - so I’m very confused! 
Y’all think I have any hopes of a pregnancy or just an odd coincidence?

Answer

I see a line on the test but can’t tell if it’s grey or pink

Answer

Definitely see a line retest in Sunday to see if it a positive and not an indent

Answer

I see a line, definitely test again in a day or so and see if the line gets darker.  It’s hard to tell if the line has any color
