Actually, that doesn't sound crazy to me. If you have eggwhite on day 20, which means you ovulate on date 20, and then get your period on day 31-33, then your luteal phase is 11-13 days long. Nothing wrong with that. Sounds like maybe you just ovulate a little late and have slightly longer cycles as a result.

have you been tracking with BBT?? Perhaps it's just more that milky white discharge that is common after ovulation.

I meant to add that its fairly eay to fix if it is a luteal phase defect (if i remember correctly) HOWEVER otherwise it will cause miscarriages (again, may be a huge generalization but thats what i think i remmebe)

Ugh, ignore the poster above.
Check out luteal phase defect.

Well you might be spending too much time looking between your legs.

How late in the game do you typically see this? And how long does it tend to last? I'm getting mine later in my cycle (day 20-21) and am worried about that. My cycles aren't overly long -- typically 31-33 days.
