I had the same problem - I had the most fertile CM in the first 2 to 3 months PP! Stressful! I even had a few "spotting" episodes at 3ish months PP.
As it is I am 9 months PP and still haven't gotten my first PPAF. I do have a continuous CM pattern, but it is not very "fertile" more of a stretchy sticky

TMI - I know!
If you fit into LAM - there is at least a 98% chance you WON'T get pregnant prior to your first PPAF. You can google if you want all of the info - but here are the highlights;
*Baby has to be younger than six months
*Baby has to be getting ALL his nutrition from your Breastmilk - no water, formula or other food
*Feed baby at least every 4 hours during day and at least every 6 at night
*You have not had a PPAF
Lack of ANY ONE of these things make it less effective.
HTH!
