feeling fine

I'm 8 weeks 6 days and this whole week i've been feeling pretty good... still a little tired, moving super slow (i feel like a zombie) and some days i have sore breasts.. i'm gassy (tmi) and that's about it. i haven't had a lot of symptoms from the beginning (which terrified me, but 7 week 4 day ultrasound showed everything was perfect) anyone else experience this? of course when i found out at literally only 4 weeks i was terrified of miscarriage, had shoulder pain for 10 minutes at 6 weeks and thought has to be ectopic, now i must be having a missed miscarriage as well. 😒 i know i overthink, just looking for lady's also feeling pretty good during their first trimester? symptoms coming and going? or lightening up?
