I'm working myself into a panic today

I have had a drs appointment in this pregnancy and a midwife appointment and not once have i had any confirmation of pregnancy or reassurance that everything is ok with baby. I couldnt get an early scan apparently at the hospital they only scan before 12 weeks if there has been a problem with the pregnancy or pregnancy before. I worked out today by the time I have a scan i'll be 13 weeks 1 day. What makes it worse is DP is away on a course the week of my scan and while he is coming back for the scan if anything is wrong I'll have to be on my own for the week. I've spoken to the hospital and the only time I can change it to is another two weeks from that date so I'd be 15 weeks by then!
I have considered getting a doppler but if I cant find a heartbeat I know it will just worry me
Just wish I could get in earlier

I tried to book a private appointment but I can only get in there the same week as the scan too
