Thank you for your query.
For me to comment on your scan, you need to tell me what day it was done.
13 mm follicle, on day 14, in a stimulated cycle, is certainly not enough for conception and implantation
Your AMH is very low, and FSH is quite high, which indicates a diminished ovarian reserve
This means that you have low capacity to produce mature eggs, and egg quality is also low.
There is no known treatment for this condition.
You have to take help of ART ( assisted reproductive technologies ) and ovulation induction
agents to produce more eggs.
Also, you can take DHEA supplements as they sometimes help in boosting ovarian reserve.
A last option would be considering egg donation
Consult a reliable Fertility
expert at the earliest, as further ageing and time would only worsen your ovarian reserve.
