Freaking out

Oh girls...I'm totally getting myself worked up. My early scan is not until next week.I'm almost 8 weeks at the moment and except for feeling more tired and hungry and the odd day of feeling hungover I have had zero symptoms. I haven't had any cramping bleeding etc either but can't help but think something is wrong!!! I'm trying so hard to relax and telling myself there's absolutely nothing I can do either way but I have no one to talk to. Just feel like a crazy person x
