6w&3d

So I'm super nervous right now I had a miscarriage back in December I'm 6w& 3d as of today & I'm just scared that I'll have another miscarriage. My boobs are still super sensitive I'm still hungry like all the time although my favorite foods have turned me off recently. I still pee a lot for me anyway but that's it. I have minimum cramping no morning sickness no back ache none of your normal pregnancy symptoms would they do a scan on me I dont have an appointment till the 28th because they wont see me till I'm 8 weeks. Is there anything I could do to put my mind at rest ?
