3 Day period

Alex • AZ🌵 Married, momma of 2, expecting 🤰🏻❤️
So on Saturday night I started spotting and then Sunday my period was heavy and Monday just a bit medium and yesterday it was just spotting. My periods usually last about 5 days, has any one who normally gets a 5-6 day period ever had this happen to them? Should I test? Or wait until next month? Help please, we've been trying to conceive for a couple of months!
