Day after O day wierd symptoms

PL

Hi all,

This is my second cycle on letrozole, and i noticed the day after O day my nipples became extremely, extremely sore and sensitive, just my nipples, which is very out of the ordinary for me. I only get breast pain a few days beforey period is due so sor nipples at all is very out of the ordinary.

Could this be a side effect from letrozole?

This didn't happen the first month I took letrozole. Anyone experience the same thing?
