3 days “late”

So frustrated according to glow I’m 3 days late, I’ve taken a couple tests and a white line appears instantly then goes away ( happened twice , are the duds? ) I’m sick of wasting tests but so confused I’ve also had mood swings and seem to be breaking out a little I’m curious if it’s AF or signs of pregnancy we’ve been TTC for 3 months help ! It’s getting depressing 😩 TIA
