😩😩😩 HELP!!

h

I miscarried a few months ago. When I got pregnant , I had sore boobs for a week, was tired and what not. After my miscarriage my husband and I took a break from trying. I found out I’m pregnant last night. Today was the day I was supposed to get my period. I took a test last night because I was crying at everything and a little cramping. But also no sign of AF coming. So now my 2 pregnancy tests say positive but I don’t feel anything besides fatigue. Is this normal? Did I test too early and maybe I’m just getting my hopes up? Also I was In the ER about 5 days ago and they did a catscan. They did a urine pregnancy test but said it was negative. Probably because it was too early. Could the catscan affect the baby? Has this happened to anyone?
