VVFL on frer but bfn on dollar store test?

Brooke

I posted earlier this morning a picture of the VVFL on my first response test. I went to the dollar store and picked up more tests but I am barely seeing a line.. maybe a little.. I’m 11 dpo so maybe too early? I got my hcg levels taken today so I’m waiting to hear back on that. Anyone else get vvfl on frer and bfn on $ tree brand?
