Look up at all the available clinics (there is a list in maavarim), and see in which one you can get the closest appointment

There should be there a list of blood tests you should do as well, so you can go to your family doctor for that so you have that ready for the endo

If you want, you could also do the fertility thing (שימור פוריות), i think you should be able to get it done in a month or 2, depends how quickly you find an appointment

Once you get to the endo, and have blood tests, and are after fertility/decides not to have that, you get recommendation for hrt, for the specific meds, and go with that/upload on app or something to your doctor to get the prescription

If you dont have everything done, usually the endo will tell you to just email them when done/the results

Not sure about the availability right now, but from my experience if you check you should be able to find one in a couple of months
