Dermoid cyst and umbilical cord cyst

Abbie

I hope some one can offer some advice as I am going out of my mind. I went for a scan at 9 weeks and they have found a 3mm cyst on babies cord and a 20mm dermoid cyst on my right ovary. I am so so scared and google has scared me even more!

I had a phone call from the foetal medicine team and the consultant wants me back in 3 weeks for another scan. Has anyone else gone through this? Im so scared x
