Cycle change after plan B?

Mariana

LMP was 10/1. Took Plan B for the first time 10/27 (not a good time to TTC that month) and got my period 11/1. It’s now 12/2 and still haven’t gotten my period. Also had EWCM yesterday and night before which usually indicates ovulation?

Anyone take Plan B and had it totally mess up their cycles?

TTC this month now so the lack of knowing my cycle is driving me nuts.
