Just need some reassurance

I am 6 weeks today

I found out I was preg at 4 weeks approx (very early) and my hcg came back about 98.

My doc was very happy with this level and didn’t order a redraw. My scan is booked for 13 Sep (I’ll be about 8 weeks).

I haven’t had any out of the normal or horrible cramps and no spotting or bleeding. Still getting neausea and sore boobs. Everything should be fine yes? And I shouldn’t worry unless I bleed or get terrible pain?

Sorry first time mummy here and just feel a little out of my depth. Friends that know that have been preg say they only got one blood test as well but just nervous for some reason I guess.
