Cyst during pregnancy

Lea

Hye all. I just found out that I have 3cm cyst at 12w6d pregnant. This is my first pregnancy. Doc told me not to worry as the cyst sometimes can disappear by itself. So, I'm all positive right now that everything will be fine. However I need to prepare myself for the worst too. Anyone has experience pregnant with a cyst? What is the do's and don't's or anyone have any tips? Thank you ❤️
