3 days late. Confused, help me. Never been pregnant before.

So I’m 3 days late, feeling extremely lethargic and tired. Yesterday I had a small brown spotting, thought it was my period coming but then the rest of the day nothing. Now this when I wiped this morning? Do you think this is just spotting or the start of my period?

Update: Took a test on my first day of missed period and it was negative 👎🏼
