A bit confused.

So I am currently 3 days late AF. I took a pregnancy test around 3 & got a negative. For the past 2 days I had a smudge of brown when I wiped sometimes none. Today it became a pale pink. I took a nap expecting Af to come but when I woke up all I had was lots of egg white cm tmi. I tested negative but maybe I haven't implanted yet or ovulated later than expected. Now on cycle day 33. Anyone else had this happen?
