8th weeks no bump seen :(

Hi all, from the chart, fetus size should be around 1.6mm but I don’t see any bump yet. Some mummies mentioned they can feel heartbeat but not for me as well. Wanted to go in for my second scan but nurse said it’s too early still… I’m still having sore breast and time to time nauseous. Tho I’ve read some miscarriage doesn’t have bleeding or symptoms. I know I’m being paranoid but any advice please? #firsttimemom
