When did your vfl become a clear positive?

Hey girls,

I tested with a vfl for three days in a row(yesterday morning was my last test).

Had 2 days of brown discharge exactly a week after AF was due. AF is now 11 days late. My boobs are soooo freakin sore and swollen (that started after the brown discharge ended), back hurts, wake up feeling nauseous (can’t even drink water and I use to LOVE water) and I’m constantly falling asleep.

Maybe the symptoms are a sign that my HCG levels are finally starting to increase? Also, any ideas what the brown discharge was? And when did y’all start getting darker lines after testing with a vfl?
