Newbie at ovulating

Kendra • Tue, Sep 04

This is my first cycle actually ovulating, I have PCOS and we used Letrozole this month and it actually worked! My question is I ovulated at cd 17 and I am 9dpo and had a little bit of spotting this morning it was pinkish. At 8 dpo I had the same thing just a little pink when I first work up and then Brown the rest of the day very very light. Could this be IB?!
