Vira,

My sincere best wishes to you at this frustrating point in your journey
What has happened to you is totally unacceptable and all the more irritating because you could have found out about it much earlier than this.

I am sorry also for the way you were left lying on the table - it's not good enough.

As Jasminstar said,

The only thing I can say is that if they haven't spotted this in the 8 years you've been TTC then possibly once it's rectified you'll be on your way to success

Perhaps this is a really positive way you can look at this? I don't want to sound patronising but sometimes I find it helps to write a letter outlining all of your grievances. Be as forthright as you want and then print it off and tear it up! It is more therapeutic than I ever knew.

We are all thinking of you and wish you all the best for your next hyst.
