Am I over reacting

I wish I would have switched. My first appointment I had I was almost 8 weeks and I got a ultrasound. My next appointment was supposed to be the big blood work appointment well they rescheduled me over a month out! Because their office “closed early”! why would they all leave early knowing they had appointments?? They called at like 9 and left a voicemail saying if I wasn’t there by 11 they’d reschedule(my appointment was at 3) I didn’t check my voicemail. So I didn’t get ANY blood work until my next appointment and I was 16 weeks pregnant!! And I still haven’t had another ultrasound since my first appointment(at not even 8wks!) and they just called today to reschedule AGAIN! luckily this time it was just a couple of days after my appointment. I call almost everyday to check on the blood work I got 3 weeks ago and they say they haven’t gotten the results back??! My next appointment I’ll be 20 weeks. I still don’t know what I’m having, I don’t know if the baby is healthy other than heart rate, I don’t know if my baby is even one baby!!! I’ve only seen my dr twice and I’m almost 19 weeks. It’s so aggravating because something could be wrong. From my 8 week appointment to my 16 week I lost almost 10 lbs. My sister in law had my niece through them and they were so great same dr and everything. Now that their main hospital is closed they act like they don’t care at all.
