I check cervical position & cervical fluid every single night in the shower starting shortly after my lochia has stopped. This way, I'm uber familiar with how my cervix feels so I'll notice any changes. Honestly, I don't even bother with temping anymore. I'm sure that works awesomely for some women, but I've found that I don't need it & find it a huge bother. I've always been able to catch every ovulation I have after each of my last 3 babies (the ones I had after learning to chart). There are always a couple times that I think
it seems like my cervix has softened or maybe opened, or other times it kinda sorta
seems like ewcm. That's the confusing part about FAM while breastfeeding. But then, I'll have the most obvious signs suddenly that can't possibly be confused. That cervix will be crazy-weird open & so soft I can barely feel it anymore, and the ewcm will be copious & stretch a mile long. There is no wondering for me when my fertility actually returns.
I had 3-4 PPAF before finally actually ovulating after babies #3 &4, and this time was surprised to find myself ovulating 1st, at 11 mos PP, then having my 1st PPAF. Followed by another O about 16 days later.
Anyway, that's been my experience.
