*TMI warning!*

Hi ladies!!
*hand in air* I'm TTC and addicted to undie-checking.

little confused with my crazy CM at the moment, and hoping someone can offer some insight?
ok - usually towards the end of the cycle i get this scary thick white sticky horror movie goo for CM. it's cd27 now (i have irregular cycles, last one was 33d so im going on the assumption that it'll be 33d again), and i have the scary goo but it just seems different... it (im soo soo sorry) smells stronger and theres so much of it i feel like i've wee'd my pants. also had some mild cramps yesterday and today. and some slight dizziness (but that could easily be from work-related exhaustion)
i do sometimes get a fair bit of discharge in the day or so before AF, but this is just crazy.
so i guess my question is do you girls think it sounds more like my cycle is going longer and i've just o'd later than i thought? or is this typical of a normal cycle and im about to get AF? (i've been on the BCP pretty much my whole period-life, and don't remember what it was like to get natural periods...)
I'm starting to worry i've missed some important BD opportunities!

Thanks in advance chickas!!
