VFL? Cycle Day 89.. 😩

Jaime • B/G Twins due July 2018! ⚾️🎀
I know this is highly unlikely, but I swear I see vvvfls on both tests I took this morning.  Currently cycle day 89, first cycle completely off birth control, no clue if I actually ovulated since I wasn't using OPKs, and had extremely light spotting (darkish brown - literally only enough to cover the tip of my pinky, maybe less) 4 days ago - first time since last AF in May.  Anyone experience something similar and actually turned out to be pregnant?  Appointment with my doc isn't for 4 weeks so I'm getting a little anxious.  Thanks in advance ladies!
