3 day period 🤨

So I started my period 4 days early this cycle. I first day at spotting in the morning and at night I had a little on the heavier side of bleeding, the second morning I had medium bleeding, and today I’m only spotting. I’m supposed to start Femara on day 3 of my period, but I don’t have a period anymore... suggestions? Advice? I’m a little confused.
