It seems to me that you do not struggle enough. The only problem in your case is keeping the pregnancy. You had two pregnancy and lost both in a miscarriage. I think that should be the center of everything. Why the miscarriage. I s something wrong with your immune system or something? Or your uterus cannot keep a baby. You have a lot of questions to ask yourself dear. Although there are other alternative that you can follow. But it could have been better if you really knew where the problem lies. Then from there you can focus on finding the solution. Remember you age is also ticking by. So you should hurry all things up. I am not saying like you get pregnant tomorrow. But the earlier you realize yourself the better. Now that you have found a good doctor. It seems the other doctors were not to your standards. Make sure he offers best services. I wish you all the best.
