Hello and thank you for posting your query on HCM
You have mentioned that you are having spotting.
If you are on OCPs, then it is a break through bleeding.
In case you are pregnant, which needs to be confirmed by pregnancy
test, it could be due a missed abortion
Spotting is not a feature of any kind of cyst
I advice to get a pregnancy test done.
Thank you and take care
