Pregnant with no symptoms 🤔

I’m 4 weeks pregnant and found out yesterday. My boobs aren’t sore. No implantation bleeding, no nothing. I feel like maybe something is wrong. I have two kids and with both of them I found out right before 4 weeks and I had spotting with both and sore nipples. Cramping with my first pregnancy but not the 2nd....Anybody not have any symptom until further along. I keep thinking maybe it’s ectopic and hasn’t burrowed in my uterus.
