clovie, I don't actually live in the Ayamonte area but I can get there fairly easily.
I have good news for you if you are moving to Spain and taking out private health insurance. It's brilliant and you don't need referrals to see a specialist, you just book it yourself. Uterine scans are included of course, they are very easy to book and better still, the gynaecologist carries out the scan personally (no sonographers) so the results are instant. Ditto the breast ultrasound that is conducted immediately after a mammogram and again, instant results because the breast specialist does the breast ultrasound personally. This should help your health anxiety no end.
I don't envy you battling the post Brexit residency requirements (assuming you are British) but at least you have the benefit of the private healthcare system!
Hi, yes! We are required to have good private health insurance as part of the NLV (The visa we are moving out on) so that's all very good news!!!

Yes the NLV requirements are jumping through hoops a bit - but we do have a lawyer in Spain who also deals with compiling all the paperwork! I'm sure it will all be worth it. Eventually!
