Should I be worried?

I had a blighted ovum in August, I was about 7 weeks and had to take some pills to pass the sack. It was physically & mentally a lot more then I was expecting and last over two weeks.

I finally got my period again on September 15th, but it only lasted about three days. For the last week now I have been experiencing what feels like menstrual cramps, sometimes just on my left side and other times on both sides. The cramps at times are intense. Is this something I need to let the doctor know or is it part of the healing process after a miscarriage??

Thanks for any info y’all might have. This is my first time going through anything like this so I’m not sure what to expect.
