What do you think??

When my period was due day 28 of my cycle I started spotting but last 5 days I never actually had my period. It was only light pink and brown spotting only. Took pregnancy test 4 days ago and was negative. Could I have had very light period this month? Or should I test again and might be pregnant? I been trying to get pregnant this last 2 months. I’m spotting so light I only use panty liner this month.
