Random bleeding? Pregnant

Jennifer

Random bleeding.... my fiancé and last had sex dec 8-9. I got my period 20-22 dec ( seemed pretty regular, maybe a little shorter than usual) then right after my period I got intense mood swings and broke out. I took a pregnancy test and it came back negative. Now a month later this bleeding when I wipe. I’ve never experienced this in between periods. Is it possible to be pregnant, I have nuva ring and I use it as directed.
