ttc after mini pill - no withdrawal bleed

Sophie 🏴󠁧󠁢󠁷󠁬󠁳󠁿🇬🇧

Hi ladies, my partner and I are ttc. I stopped the mini pill on 23rd June and have yet to have a withdrawal bleed. My boobs have been sore and have had slippery cm the past few days. Possible ovulation? I have no idea when to expect a period as have been irregular on this pill. BFN this morning. Input would be great ladies!
