Spotting with letrozole

Destini

Did anyone take letrozole and start spotting a few days after finishing? I’ve been spotting since yesterday, it seems to be old blood (sorry tmi), super dark with little clots in them. My doctor said spotting was common, but if it became more like a period to come back in. Anyone else have this happen? I kinda thought it would be gone by this morning, but still here!
