Nervous/scared

Alexandria

I’m 17 years old, my last period was June 19th so it says I’m around 6 weeks and 3 days pregnant but I don’t know for sure and I went to the er they didn’t do a ultrasound or anything and I haven’t told anybody but the child’s father who lives with me and my father. I have literally little to none symptoms. I have fatigue and frequent urination and I feel a little bit nauseous when I first wake up but only for maybe 5-6 minutes and I’m paranoid that maybe I’ve had a miscarriage or a missed miscarriage but I have had no bleeding or nothing I’m just scared. I don’t have food cravings or nothing. Is it normal not to have morning sickness at 6 weeks or is that bad
