Hi there, I noticed that when I started to actually pay attention to my cycles they seemed to go to pot!!
I used to be a regular 29 day cycle...up until the few months before ttc then they went all over the place.
If you look at my FF chart (click on fertility friend at bottom of my post) I had a bit of light spotting 4DPO then spotting started again 8DPO until AF arrived 13DPO making mine a 25 day cycle
It could well be implantation bleeding, but I never used to pay attention to CM or stick my fingers up there that often until I started to chart so maybe your just noticing more things that normally you wouldnt??
Good Luck, I hope this is your
Emma.xx
