23 weeks and 5 days FTM

For the past few days I’ve become nauseous and slightly dizzy. I’m also seeing floaters randomly. The next time I see my doctor is October 7th. No swelling in hands or feet unless I’m in the heat and walking a lot. I’ve been getting 80oz of water a day. Should I be worried or is this normal in pregnancy? I know symptoms come and go. Thank you in advance for your advice.
