LMP was on 14nov 2016, had physical on following months. In Jan 1st week my Partner ejaculated on me. Did UPT on 9th it was negative. On Jan 14 again I had period but that was only for two days. What I'm worried is whether that is period or spotting as in medical terms. Do I need to do UPT again??the amount of blood was not that less. And it is red in color and with little clots. Today is the third day and little blood was there.
