Hi, KattyK. I'm really sorry that this journey is so difficult for you. but you're not standing still and it's good.
Regarding a clinic choice, there are so many things that play a huge role in the process, and no one could tell you what is the best for you. I should defo trust your guts. I mean if you think the first clinic is that bad, then why you're thinking about being with it? or maybe you know that your negative experience was kind of a hasty conclusion made without real reasons? I see that you are really concerned about little things and maybe you'd better try to assess the situation once more? think of pros and cons of every clinic one more time and compare positive aspects. wish you lots of luck!
