I heard this term from a cousin who went through something like this and it scared me. I have my first scan next week and now im a bit worried. What does it actually look like on a scan or how do they find it?
My doctor explained it is an abnormal growth where the placental tissue develops wrongly, and the ultrasound shows a distinct snowstorm or grape like pattern. The hcg is often unusually high. It needs prompt medical management, so a scan is the only real way to know.
I went through something like this and on scan it looks different, often described like a cluster of grapes rather than a normal sac. Symptoms can include bleeding and very high hcg. Please dont diagnose yourself, an early scan with your doctor is essential.
I am gentle about this topic. If you are worried, please go in for a scan early rather than searching images that scare you. The doctors handle it well and you will be looked after. Take care of your heart too.
