Not much symptoms at Week 5 with no implantation bleeding. Is it normal?

Hi all mom & mom to be! I'm currently at week 5 (as per app) and waiting for my gynae appt scheduled for 2 weeks later. Don't have much symptoms yet and don't feel pregnant. Did a HPT 4 days ago and found out I'm pregnant. My 1st pregnancy, definitely excited yet worried at the same time given the high miscarriage rate in 1st trimester. Read up a lot and got myself stressed over it. Anything I should look out for? Is lack of symptoms normal at week 5? My nipples were v sensitive and quite sore the past few days but it suddenly goes back to normal. Should we create a WhatsApp chat group too for Feb 2024? 😁
