35 days since last period?

I’m currently 16 days late for AF. I’ve been having very light spotting maybe once a day to every two days. I’m tired, faint, teeny tiny cramps -no where near what my period cramps are normally-, moody, I don’t enjoy food anymore unless I’m absolutely starving, and it takes one second to go from ‘I don’t want to eat’ to ‘FEED ME OR ILL KILL YOU ALL’.

I had a miscarriage at 8 weeks in late October and have had 2 completely normal, regular cycles since then- same CM patterns, symptoms and everything.

I’ve taken 6 pregnancy tests, three clear blue, one of those looked as if it had a VVVVFL, so I bought some first response, all were negative. It’s been a few days and still no AF or even any signs of her showing her ugly face. I’ve got a few confirm tests so I’ll take one and see if it says different- chances are it won’t.

Does anyone have any idea what could be going on? I’m so confused and desperate for my rainbow....

UPDATE: confirm brand test is oh so negative.
