Did I ovulate??

This is my second cycle on letrozole because I didnt ovulate the first time taking it. Today is cycle day 16 for me and on cycle day 13 and 14 I had really really wet and slightly stretchy cm, and yesterday cycle day 15 it was really milky and today nothing at all. On cd 14 my cervix was high open and soft but last night it was medium high, soft and open. Did I ovulate already or am I getting close to ovulation??
