Experiences of very early pregnancy symptoms??

This month my cycle symptoms after ovulation have seemed very different to usual.

A few days before ovulation was due, I had sharp cramps on the left side of my tummy at night on CD12 that went away after around 15 minutes. Since ovulation I've had milky discharge every day & cramps on & off in my lower tummy from CD20 to CD23.

AF is due in 6 days so it's too early to test, but has anyone else had/known of symptoms like these ending up with a BFP?
