10days black blood period after abortion

Hello,  I had medical termination of 8weeks 2days pregnancy using pills. 1st set on 10Dec22 & 2nd set on 12Dec22. I bled heavily, passing large clots in first 24hours. I did a transvaginal ultrasound 3 days later (while still bleeding) I had no fetus but 32mm of RPOC. I bled continuously for nearly 2 weeks, twice passing very large clots but generally the bleeding got lighter with time. Then bleeding stopped completely for 2.5weeks. I had a slight white discharge for a couple of days so I did another transvaginal ultrasound on 10-Jan-23 and it showed that I had ovulated and I had 10x7mm of RPOC so was advised to wait for my periods to flush it out.  On 14-Jan-23, I got what I assumed was my periods but was lighter than my usual periods and it was only black blood. I'm still bleeding  out black blood lightly but constantly till today. But I have had no cramping/belly pain/fever, no green or yellow discharge. Is the light bleeding of black blood for last 10 days my periods? Or infection?
