Confusing period help!! - update!!

So I started my period on November 12 and it lasted for only three days so until the 14. I was on medication from November 12-20 for bronchitis. On around the 20th I had brown spotting for 3-4 days. I’m now starting my period today, which is early. I am NEVER early! ***my period only lasted for 3 days again, 2 days heavy and then 1 day of spotting and now nothing...***

Just curious if this is normal. I’m super stressed out with work and grad school and coaching. Also a virgin so there’s no way it’s anything else.

Just concerned!!
