Amillia

So according to glow my period wasn’t due for another 5 days and I started spotting. The next day it was a light to medium flow but I still didn’t completely saturate a tampon. And the third day it was very light as well completely stopping in the evening. And cramps as bad as period cramps. Was that my period or not? I’ve never had a period that light before.. should I take a test?
