Vvvf lines for several days

Brooke
Hi All:  I've taken way too many HPTs over the past four days.  I had a miscarriage last month and my levels were confirmed to be back at 0 and doctor encouraged us to try again.  I ovulated around April 9-10 per LH surge and I can't really say when AF is due because of my MC.  I see vvvf lines but today being the fourth day I assumed they'd be much brighter and they are the same.  I also took a gold digital and it was negative.  I'm so confused.  I know I should just wait it out and see if AF comes but I'm struggling to deal with the idea of a CP right after MC.  I have taken FRER with vvvf lines as well, but today there was no visible line not that test but a vvf positive on the wondfo test pictured.  It just seems so off since wondfo is supposed to be hcg 25 and frer hcg of 6.  Anyone have similar experiences?  My cycle is typically 32 days and I ovulate late at day 20.  My LP is usually 13 days.
