7w3d spotting & have an ovarian cyst.

So I found out I am expecting 3 weeks ago with my 7th pregnancy, 4 miscarriages, my son 6 & my daughter will be 4 next month.

A week later After I found out I am pregnant I started spotting, today is the 10th day of spotting, nothing on pad, just when I wipe, no pains or anything.

I had IUD for 3 years, was removed November 2019. but I was told I have a cyst in my Ovary.

they did a blood work last week, I am due for another blood work this week...

What might be the cause of spotting?
