Worried

This is my first pregnancy and we were so blessed to have conceived on our first and only try! I am excited but scared as hell for this tiny human I’m growing. I had symptoms up until 4 weeks exactly then started to feel very normal. This is scaring me. I had 4 positive tests and my period is 6 days late. So, are little to no symptoms anything to be scared of? My mom had a couple of miscarriages and an ectopic so I’m afraid I might have the same. My first ultrasound is May 8 and I don’t know if I can wait that long!
