Opinions? Has this happened to you?

I lost my baby on Nov 17th.

I started bleeding on the 11th which was very light brown spotting.

Confirmed I miscarried on the 17th and bled red blood till about the 24th if Nov.

Now I started spotting this month on the 18th but I only bled two days very lightly and that was it.

Not my normal period.

Usually I bleed for 5 days.

My fiancé and I have been sexually active but I don’t know if this or normal.

I have heard it could be because my uterus hasn’t healed.

Any opinions?
