Should I go spend money on a FRER test? My SO hasn’t worked in almost 3 weeks now because his dad is dying and he’s been caring for him... so I’ve been super frugal and don’t want to spend $20 on a test and just have it be negative. But I’m also dying to know if it is positive. Both of these tests were from this morning? Pic taken at the 5 minute mark. AF is 4 days late.
