Need experience advice almost 8 wks

I probably shouldn’t be thinking about these things ... but maybe reading everything on this site sometimes makes u paranoid but also it’s great to gain more knowledge. I’m at 8 weeks now and been pretty dizzy pretty much all day , very very sore breasts , and bit of nausea in he morning ( even before pregnancy if I had too much acid in my stomach , morning after I would be very nauseous till mid day ) occasionally abdomen pain , specially when I move wrong or cough ...

My question is , and may not have an answer .. but for the ladies who have had miscarriages , you would still have all these symptoms even if you never got a heartbeat right ? Bc the sac could be formed and everything with hormones increased but didn’t progress ? Or do you feel different or that something has changed ? I should try to relax and wait till my first app this Friday , but I just wanted to get some advice .. it’s really hard not knowing what’s happening and I know I’m not the only one with the wait ... thank you so much for any words ..
