Anything?

Trying to stay positive. Thursday morning I took a test and was able to see a vvfl. I’m still seeing a vvfl, but it’s not any darker According to the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> I’m 19dpo but I know that can be off because my cycle is always wacky. Can you see it? Any positive stories with vvfl? My husband and I have miscarried twice. And this would be our first successful time since the last miscarried. Worried!!!!
