Femara and spotting?

I am currently on cd 13, just had an ultrasound this morning to check the follicles (1@12cm & 2@10cm) so I’m not ovulating yet. Next apt is Monday to see if I have to take the trigger. Yesterday when I wiped it was thick cm with a brown tint... is that normal with femara? I don’t think I’ve ever spotted before mid cycle.
