AF is late by 3 days

CD 45 today

The day before AF I was having strong cramps so I I thought AF was coming.. it never showed. I woke up this morning at 2am with cramps, I prepped myself getting ready for AF and couldn't fall back asleep until panadol kicked in an hour later.

AF still isn't here? I've takek test after test and all are BFN (one false positive)

Has this happened to anyone before?

If I'm not pregnant just give me my damn period already to save me the hope and disappointment 😔
