So I have spotted for 4 days now

The first day it was really light then later that night got a bit more darker thinking it was my period then the second day there was no spotting the third day went back to light spotting and then the last day was also light and now I’m no longer spotting ? 🙃 kinda worried and I’m not the type to spot in between periods either plus I experienced nausea and cramps during those days . Hellllp and I missed a month of my period last month
