Ok glad it's not just me thank you :)
I have noticed the same!! Also had a baby 5 months ago and my periods are regular again and also have had some spotting during ovulation. Never had this before baby either. Weird right! But glad to read I’m not the only one haha!
I had my baby in December via emergency c section and I’ve noticed I’ve been spotting (in my discharge like yours) not sure if it’s around ovulation as my PCOS has flared up again so cycles have gone haywire but my mum also said after her c section with my older brother, she spotted around ovulation too x
