feel so frustrated , any opinions ?

on Saturday at 8am I got a faint line on a first response test, today I took one and I can’t see anything that I know of at all!!

Then last night I went pee and also had some pink spotting as well which I’ve never had before !

I don’t know what’s going on but it’s so frustrating! And I always counted on first response as well because I know their trust worthy!

Also my period is due in 3-4 days now.

Any opinions?
