Nervous nelly

So AF was due yesterday, but Sunday I took a test and it was positive to really be sure I’ve taken like 5 more since Sunday all positive. I have a doctors appt to confirm the pregnancy on Friday, but I’m still so nervous that I’m not. My boobs have been on and off sore plus I haven’t been able to go to the bathroom, but those are really my only symptoms. I know everyone is different just still feeling nervous. Is this normal to not have too many symptoms so early on?
