I had a much bigger cyst (over 6cm) and it had a strong structure, not fluid. at first it hurt like hell when the uterus was growing fastest. I have to monitor the cancer cell markers every month. after two months of pregnancy (I'm 16 weeks now) my doc said the cyst practically disappeared! don't worry! pregnancy is the best cure for the cysts!
Drink aloe Vera water. My cyst went from 6 cm to 1 in less than a month.
When I got pregnant with my 2nd child I had cysts on both my ovaries they went away after about 5 months of being pregnant
