Implantation…? Or ovulation?

[Aishhhh]

Longish post (sorry)
Hi everyone, so just for a little bit of history , ive got two children (4&5) first conceived with clomid , second one was a surprise, i have used protection since then & recently decided to try for a baby.
FYI- i was overweight & had non existent periods with my first two pregnancies
i have since lost all my excess weight & have had a regular cycle for the last 2/3 years.
i had sex twice in my fertile window (4th & 6th May)
this morning i had pinky discharge, too soon for periods, maybe to early for implantation but never something ive experienced around the time
of ovulation before.. i have purchased ovulation kits & will use it next month if it doesn’t happen this month, just wanted to hear from anyone , any thoughts would be appreciated 😊

How much too early for your period are you thinking it is?
I had implantation bleeding start on the Friday when I was due on on the Monday. But I suppose if you think your fertile window was earlier this week that would be quick...

according to flo, my fertile window was from 3rd-9th May, my period is due on the 23rd of may, im not sure how accurate this all is because my period is always 3/4 days late each cycle.. maybe what im feeling now is due to ovulation, & not implantation? Im honestly so new to calculating all of this so im unsure on how accurate flo is with ovulation
