5 days late!!!! HELP

Allison • TTC baby #1 Since 2016. Diagnosed with MFI in August 2018. First IVF round started in November. Transferred TWO, 5-day blastocysts. Positive beta on 11/27 (426). Next step is ultrasound on 12/11.

I've never been even a day late before and now here I am 5 days late. I heard it is common for women to get bfn's until they're 8+ days late, anyone have that happen to them?

The original test has a "shadow" in person slightly. I think I see something in the inverted?

Very nauseous, had cramping for the first 3 days I was late.
