@Violette22 what country are you in?
Adhesions are bands that attach the uterine walls together, they can occur with chronic endometritis. You didn't have the bacteria commonly associated with the condition (that's what the ALICE tests for), but I think it is still up for debate as to what bacteria can cause chronic endometritis.
It's always worth doing imaging like a HSG or saline scan in any case. Structural issue can be missed on ultrasounds.
In my first EMMA I had 0% lactobacillus, I was treated with 7 days of co amoxiclav, and followed it with a huge amount of vaginal and oral probiotics. I got rid of all but the gardnerella, which unfortunately flourished.
On my second EMMA I still had 0% lactobacillus. I then did the treatment plan I wrote here. I really would have a look into the vagina acid tablets if I were you, you need an acidic pH for lactobacillus to adhere to the walls of the vagina and it's lactobacillus that creates that, so in the absence of any lactobacillus you will benefit from creating it.
For my third analysis I did a menstrual fluid microbiome test, they didn't give me a percentage but lactobacillus was stated to be "very high" I asked what percentage that is and I was told by the company that it means above 79% and could be anywhere up to 100%.
Since there I have kept an eye on my vaginal pH which has been below 4.5 for a few months now. This means my vaginal microbiome has a lot of lactobacillus. Garnderella flourishes in high pHs.
