Was that my period?

We've been TTC for 11 months. I was 4 days late when I started my period (friday) but now today (sunday) I am unsure.

My typical cycle is 4 days. With day 2 and 3 the heaviest. Friday was just some brown spotting, Saturday was red bleeding but way lighter than my normal and slowed to just some brown spotting by Saturday evening. Today, Sunday is just barely any spotting at all and is brown. I hardly had any cramps. I've never had this before..

Anyone else experience this or know what this was?
