Okay, while I agree with the women saying to stop researching, I am shocked by some of the other opinions.
1. The internet is here for research. You were told your baby has a cyst. Of course you are going to research it. It is something you are not familiar with and need more answers. On the other hand, the internet can lead you to false information or a very scary diagnosis that is probably not the case.
2. You are a mother...you are going to worry. No one should tell you not to worry. That is your job as a parent. On the other hand, be patient. You should put your focus on your two children and eating healthy.
3. No one should put their opinions on medical tests and equipment on you. Ultrasounds are very effective and important tools to help determine multiple things during pregnancy...weight, length, abnormalities, and other conditions.
4. You have a right to be scared. I know I would be. I do agree with what some of these women are saying. If your doctor doesn't seem to be concerned right now, that is great. Trust your doctor unless he/she gives you a reason not to.
5. A cyst can be a number of things, including something scary. But it could very well be something benign such as fatty tissue.
My Sister in law had an ultrasound done during her 20th week. They found a cyst on her forehead/nose in between her eyebrows. They said it was a benign cyst and to watch it for a few months it could go away. However, it did not go away. They did have to do surgery to remove it when she was a year old. She has no scar, no side effects, and is perfectly healthy. When her cyst was found it was 2mm and it was 2.5mm when it was removed.
Keep doing your research. Write down all of your questions so you can discuss what you are worried about at your next appointment. Your doctor will give you all the answers you need/want to your questions. Explain your fear and anxiety.
Let us know what they say! You are in my thoughts. Good Luck! Best wishes!
