A lil vent

So this is my third pregnancy and my first ultrasound was when I was 7 weeks 1 day I am now 15 weeks 3 days and have an appointment on Friday which will make me 15 weeks and 5 days! And they call me to confirm my appointment I said I'd be there of course and i also asked of I was scheduled for an ultrasound and she said no maybe next time and told me see you Friday have a nice day. Personally I'm pissed the hell off this is my rainbow baby and everyday still I'm scared and want to make sure everything is ok all I want is a peace of mind. I also am going to ask for a mid wive again bcus I never get the same doctor and its very frustrating to see someone who doesnt know me and check me for things I have to repeat everytime I'm so annoyed
