Should I be worried ?

Im 7+3 days , okay so my symptoms are , occasional nausea , some cramps, I get up to pee all the time , I even go before , mid sleep , and in the morning when I wake up , I'm always tired and hungry but my breast don't hurt that bad I do wear a pretty supportive bra and can kind of tell their getting bigger , same with my stomach( of course bloat) maybe it's my mind running me crazy , I've been pregnant before but only lasted 6 weeks . Then ended in a miscarriage , what are my chances of having another it's been a year or so , i have an appointment on my 8th week and nervous , I hope I see a heart beat . Can anyone give me a little reassurance ?
