Oh muminwaiting I am so sorry for what you have been through. That is terrible, and very inconsiderate and unprofessional of your hospital.
I can sympathise, I had 4 consecutive mc's after my DD, and they left my world turned upside down. I am having counselling to help me cope with the grief, and only today I used the exact same words you have use "I wouldn't wish this on anyone". So so true.
You haven't done anything wrong at all. All you have done is put trust in your doctors, and have listened to them. You have put your trust in your doctors, which is what ANY woman would have done. It is just unfortunate that they haven't given you the support you needed.
Blood karyotyping should take around 6-8 weeks, and the blood clotting tests take a bit longer. In all, you should have had your results back in 3 months. Like the others have said, you need to start pushing your GP and your consultant for results now. It's really sad, but alot of the recurrent mc sufferers I have met on here have had to lead their own treatment.
Make an emergency appointment with the GP and tell them of your ordeal, and don't ask them to ring the consultant TELL them to ring the consultant, and email him everyday until you get an answer.
This is totally unacceptable and I am really angry for you.
If you'd like any kind of advice about tests or treatments please feel free to PM me, or there are other women who have been through what we have been through on the recurrent miscarriage thread in this topic. You will be given loads of advice about what to do there too.
I must say, your husband sounds like a gem, and you are very lucky to have his support through all of this and you will get through this, I promise you.
