booking appointment uk

So, I went to the GP and was given a number to ring to book my booking appitnment with a midwife. 
I ring up and the receptionist says I'd be best going to a group booking appointment! I said no thanks, I want an individual one. I've had a miscarriage, which I wouldn't feel comfortable discussing amgonst other people I don't know and who don't need to know! 
And my boyfriend already has a child who is severely disabled, I don't want to discuss that with other people who don't need to know either. 
So now I don't have an appointment because she told me there was only group ones left! 
So angry!!
