hiya
I have PCOS so i get them all the time, just looked through my notes for you and at my first scan at 7 weeks it showed a cyst on my right ovary that messured 3.2cm
Then at my 12 week scan it messured 3.6cm
I had a scan at 16 weeks and at 21 weeks and there is no record of it in my scan notes so im guessing its gone.
It didnt cause me any bother whats so ever, i didnt even know it was there untill they told me, but the hospital were not worried atall.
Hope thats put your mind at rest a bit
