Just need some reassurance 😕

Can anyone reassure me that this is normal??  I am 10+4 today, my first pregnancy after 11.5 years ttc. I'm freaking out slightly that I have no real pg symptoms - no real nausea, no morning sickness, no darkening nipples - I'm just exhausted and don't have a great appetite. Also my boobs aren't aching quite as much this week as they were at the start. I had a scan last week and everything fine, next one is in just under 2 weeks.
