Dear Shyna,
I'm sorry about your miscarriages. I've had plenty of my own and know the depth of the heartaches that go with them. I recommend that you find a miscarriage specialist so you can get medications that could prevent miscarriages and make sure they get caught early. Don't go to just any gynecologist. A miscarriage specialist would also probably have more interest and empathy for you.
As for the emotional support, physicians and medical staff worldwide are not trained to give emotional support. Things are getting better, for example, when I had a miscarriage in Boston, they asked me if I wanted to speak to a counselor, but Japan would lag the West anyway.
As for appointment times, appointment times are a joke in Japan. It's better than it used to be, but they don't count for much. Even in the US where I live now, depending on who I'm seeing for what, I can wait over an hour, or the nurse sees you quickly and takes your blood pressure, but the actual time you see the doctor is an hour after the stated appointment. Were you being discriminated against? Possibly. I think we all put off things we feel uncomfortable doing until the last. Most Japanese doctors have atrocious English skills, and I bet they don't care to display their lack of English in front of the other patients or nurses. Hence your doctor saw the other patients first, a willful procrastination, rather than malice or prejudice. One way to alleviate this might be to find a Japanese friend to go along with you who could translate and to diminish the discomfort of the doctor. I'm not saying that what he did was right, but it would alleviate your suffering, too, to be seen early, rather than late.
A miscarriage specialist might also have better English skills, and will make sure you get monitored frequently. I had to adopt in the end, but at least I feel confident that the doctors did all they could for me, and I have no regrets. You need to get the best care possible, too. Good luck!
