Kindly help me to correct these sentences

[Annecy]

As we are planning to do the medical treatment under your consulting, we need to know when we should come. Should we plan after three months has been completed?
However, we do not want to do any further treatment here after twelve weeks because of previous loss.
We were planned in the beginning, the treatment would have been done in our home town as early as possible, but unfortunately we couldn’t make it out.
We were totally confused about the decision for travel once this scenario has been noticed that is why we advised your opinion.

Our original plan was that the treatment would have been done in our home town as early as possible, but unfortunately we couldn't arrange this. In our current situation we are confused as to what our travel arrangements should be, which is why we have asked for your advice.
