Yeah, the antibiotics were very strong, specially the ones usually prescribed for both conditions you had. Your gut flora definitely took a hit, so the diet and the probiotics are a very good idea. Check out to see if the probiotics contain lactobacillus rhamnosus, ideally the GG kind. If not, that is okay. But ideally, your next bottle of probiotics should have them. It encourages a good neighborhood in general. If you tolerate sauerkraut, that will be a good addition to your daily carb intake.
I would check for iron levels if you haven't done so: TIBC, iron, ferritin and transferrin. If you don't have iron overload (transferrin >35%, ferritin >80-100), I would take vitamin C. It will help out along the diet. Also, make sure your vitamins contain NO iron. If you don't have anemia due to iron deficiency, then, any excess iron will only harm you.
Not too long ago, I had a dental abscess. I started taking megadoses of vitamin C immediately and the abscess dried out without the need of any antibiotics. It is really great stuff! I chose to have plain ascorbic acid every hour, to bowel tolerance. I think I reached 20 grams or so per day until the abscess dried out. Not too bad!
As for hormonal support, the diet goes a long way. It takes time for re-adjustment, but if you feel you need extra help, then progesterone cream for a couple of months is something you can experiment with.
You went through a lot, I'm just glad that you are taking proper care, sharing and reading about it.
