What is up?!

Cecile

So my period is now 1 week late, I am usually super regular 27-29 days for past 5mths. Before that occ. 31-32 day cycle but very far and between. We gave up TTC this month and didn't try time intercourse around ovulation. I stopped tracking cm, using opk and track symptoms etc religiously so can't even go back and check 🙄 I remember one week after I should have ovulated I had crazy "fertile" mucus and was like "wahhh this is weird" we had spontaneous sex that night. I took a frer test last Friday and on Wednesday, both BFN. What is up?! Should I risk testing again, do I just wait it out?! Feeling so lost and confused...

***Update*** I got this, this morning! Is it positive?!?
