Trying DIY because my country is highly inneficient and stupid

After a couple of tries to get hrt with SUS, brazils public health system, I decided to try hrt because I keep running into problems with their system (first time I tried the doc didn't even know HOW to start the whole process, so I got put into the wrong system, second try they changed my appointments date without telling me, third try the doctor wasn't avaliable and I had to re-schedule) so now I want to try DIY at least while I try to solve this whole issue.

Problem is that while I know the best way to do hrt, it's something I would have to buy from outside the country as injections (with the exception of perlutan which contains progesterone) are not legal here so I would have to buy it in dollars which would make it very very expensive, but other methods such as gel and pills are avaliable here pretty easily and while still expensive, it's better in the short term while I manage to get it through SUS. But when it comes to getting a good dose of these I'm a bit clueless.

I wanted to try Primogyna (primogyn) because gels and patches seem to suck a lot considering how fucking hot it is here but I don't have a good idea on the dosage I should try. So far, I've seen people saying 2 mg every 12 hours work, but some peopel say it's best to use 2mg every 8 minumum, some people say it works sublingualy while others say it doesn't and so on. I wanted to know if there is anybody who tried it and how much they took it/how they took it.

Also, yes I plan to move to injections eventually, but when I get the money to do so which might take a while considering how messed up this country is right now
