Ellie,
What a rollercoaster you are on at the moment. When I had an early scan at 7 weeks, my FS told me not to freak if there was no heartbeat. Hang in there hun. As for molar, I'm not too sure but isnt that a cell division issue I dont think you can have a molar with IVF. But I'm sure someone knows more about it than me
