I went in for an ultrasound at 5 weeks gestation I was told to go back at 8 weeks so I did for another ultrasound at my check up after my 8 weeks ultrasound I was told I had a 3 mm cyst on one of my ovaries and scarring on my bladder I'm not worried about the cyst I'm worried about the scarring on my bladder has anyone ever had that before the doctor told me I could possibly need surgery but not to worry that was at eight weeks I got a call today and they said they want me to come in at 12 weeks to check on the scarring on my bladder I don't understand she told me not to worry why is she having me come in to check it out
