What to feel at 12 weeks??

So I have a question for you ladies.

Tomorrow I will be 12 weeks and for some reason I have felt “lighter” I don’t my baby bump like I used to. Maybe it was due to bloating who knows. Náuseas are gone. In a couple of words I don’t feel pregnant in a way. Maybe due to the symptoms I was getting before that I’m not getting now. Also people that have had kids before keep asking if I have felt this tingly sensation (already four people asked me the same thing and my answer keeps saying no) Is this normal what I’m feeling? Should I be worried? I also suffer from PCOS maybe I had a silent miscarriage? What should I do? What should I be feeling at my 12 weeks pregnant.

Note I understand all bodies and pregnancies are different. But this is my first unfortunately i have nothing to compare it with 🤷🏽‍♀️ thanks!!
