Yes I started the 19th and I still have bleeding now but not as much and blood clots.
Are you sure your "2 day period" was from the vagina?
With having frequent urination, you may have a urinary infection and the bleed may have been from the urine.
If you continue to have frequent urination, make an appointment to see your doctor to check for a urinary infection. In the meantime, make sure that you drink plenty of fluids and especially water.
It is quite normal for periods to fluctuate a few days either way.
