Mid-cycle spotting? CD8 on Letrozole 💕

Hi guys

Sorry if this has been asked before

1st cycle ....cd8

I'm on Letrozole 2.5mg cd 3-6

My period stopped CD4

This morning I woke up with a tiny bit of spotting, dark red blood not heaps just when I wiped and a tiny bit on my pad

Is this normal? Sorry ladies if it's something someone asks all the time, just wondering if anyone else had this? Or does it mean I'm out? A bit confused 😕

TIA for replies 💕
