Anxious

Hi I'm 8 weeks 6 days had a few early scan through sheer paranoia.. Last one was Monday baby had grown heart beating strong but I'm so worried last two days I haven't felt as crazily hungry as I have been and boobs not hurting that much.. I no symptoms can come & go plus I'm coming down with a cold not sure if that's making me not have an appetite.. Just after a mmc I can't help but worry over every little thing :(
