I'm 38, my tubes are tied, the last 2 months I spotted before my period. This month I spotted for one day, the second week into January then a week later I had my period the, the whole time for 3 days while on my period I was cramping and throwing up, and also weak, which was not normal for me, now the forth week of January I have been spotting so far for two days.

What does this mean?
