So my new norm lately is being irregular for the past (3yrs). But for the past 4 months I've been regular give or take a few days. So this month my af was supposed to come on the 4th or 5th of this month but didnt show so I figure it would come in few days no biggie. A week went by still nothing ,the week after I took a pt & it was negative. Ok cool figure it was going to be 1 of the past afs I've had.🤷‍♀️ Now this past Sunday go 2 work and get off & use the restroom b4 leaving , I seen pink spotting ( I normally would be able 2 smell if my af was bout to come but didn happen plus I was wearing work out pants so I definitely myself or any1 could smell it 🤷‍♀️) so got home prepared 4 in comin af but Monday :nothing, Tuesday: I had brown discharge on could only see if I wiped , Wednesday: brown & very lite pink discharge only wen I wiped , Thursday: mostly brown & pink discharge only wen I wipe. Friday: very faint pink & b4 5pm it was done but I could smell blood since then is it me with sensitive nose or something else.

Question is What does this mean?

Is it implantation ?

I'm scared to test I've been ttc for 3yrs🌈
