No pregnancy symptoms! Is something wrong?

Backstory: I had a miscarriage last year in November (found out in my 8wk appt, it happened in week 6). I had severe symptoms almost as soon as I got pregnant. Sore boobs, crazy fatigued, and nauseous and the symptoms started exactly in the start of my 3rd week.

Well I just found out I’m pregnant again, and tomorrow will start week 4. I have absolutely no symptoms. Kinda tired here and there, every other day I get exhausted around 4pm. Other than that, nothing. I’ve read that this can be normal, but with my miscarriage history I’m just so nervous that this means more than what it is. Has anyone experienced this before?
