Hi Sofib - I'm sorry you had such a horrible appointment - I honestly don't know what gives some doctors/consultants the idea that they can behave like that. And it's so bloody intimidating/crushing if you're in a vulnerable situation to start with.
I agree with advice to go back to your GP, and ask either about another clinic, OR, perhaps more realistically, seeing another consultant at the same clinic.
I say that only because your access to other clinics is going to depend very much on where you live. Also, if you are able to be referred to another clinic, I guess there's a chance they might have to start from the point of referral again, i.e. GP's letter - which will mean more delay.
Re: fertility treatment over 39 years - what's available on the NHS varies from area to area, both in terms of the upper age limit for access to IVF, and also in terms of the number of cycles. [e.g.NICE guidelines recommend 3 cycles - some NHS trusts offer 3, others only offer 1]. I don't know of any trusts that offer NHS treatment beyond 40 - NICE guidelines say it should be available for women up to 39, but in some PCTS, I believe the age limit is even lower.
So I'd suggest you find out the access criteria for fertility treatment in your local NHS trust. This is publicly available info. Then you will know what you can ask for.
In all honesty, your options at this point are going to depend very much on whether you are able to pay for private treatment. I feel horrible typing that, and I wish it wasn't true, but that's the size of it. If you can only go down the NHS route, you might need to get very 'pro-active' about pushing for apppointments and trying to speed things up as far as you can. If they will only give you treatment before you are 40, but won't have completed tests to decide what treatment best suits you by then, where does that leave you? [question for consultant, obviously].
If you can pay for appointments/treatment, you get seen and tested a lot faster. At my 'local' IVF clinic, the NHS waiting list for an appt is 6 months. If you can pay, it's 4-6 weeks. They also only treat women who are under 40 (which means you have to be under 38 and a half years old when the doctor refers you). However, private patients will be seen up to age 45. You see what I mean.
So I'd say, check out the access criteria for NHS fertility treatment in your area - have a look at prices for private treatment at a clinic and see if that is an option at all - and ask if you can see another consultant.
And I know it isn't what you asked - but I think the fact you have recently conceived naturally, albeit sadly then miscarrying, is a very positive thing, fertility wise. And while I totally understand why you have sought fertility treatment, and that is the advice - it's really common for 39 year olds to take longer than a year to conceive naturally. I don't want to sound glib, but FWIW I think your chances of conceiving naturally are still pretty good.
Good luck.
