has anyone ever had this happen? and what came of it?

I had a period on the 14 of December, (miscarried at 3 weeks) and I just had what I guess you'd call a period on the 1st of January. it only lasted 3 days and was a little less than normal flow, but I had a couple small clots. my periods are usually about 6 days long so it's very weird that this month was only 3 days. coming off of my period, I have all these symptoms that I only ever get if im pregnant. (hunger, frequent urination, sore breast, veiny breasts, fatigue.) but it obviously isn't that because I just had my period. anyone else have this happen before?
