Concerned...

So I am currently 8 weeks and I had my first appointment Friday. I came out of that appointment so confused. I didn’t get to hear the heart beat or have an internal ultrasound, no bloodwork, nothing. She literally just told me my due date based on my last period, which any one could figure out without paying to see a doctor, and sent me on my way. My next appointment for an ultrasound isn’t until almost 13 WEEKS. Like what if something is wrong??? And seeing everyone else having ultrasounds at 7/8 weeks is making me feel scared. The doctor acted like I was crazy when I asked. I am in Ohio, anyone else experiencing this?
