Sheenas7,
I am not aware of any study done to estimate the optimum timing of when to get the booster after recovering from Covid. But, you may find the linked study below interesting.
Here is what I find striking. This is for those who had recovered from Covid and who had not been vaccinated. What I find interesting is that comparing the survivors 6 month memory B cells and their memory B cells again at 12 months, is that they evolved to produce a more broad and potent range of antibodies. See the second bolded text below from the linked article.
"Compared with 6 months prior,
participants who were not vaccinated maintained most of their plasma antibodies against the virus’s receptor binding domain (RBD) and their plasma had similar neutralizing activity against a nonreplicating virus engineered with the SARS-CoV-2 spike protein.
Their memory B cells that produce anti-RBD antibodies were only slightly lower in number than at the previous visit and had evolved to produce a broader and more potent range of antibodies."
But, making the case for still getting vaccinated after recovery is this. Keep in mind these are folks who had recovered and then had one vaccine dose.
"Compared with unvaccinated participants,
those who had received at least 1 dose had higher plasma anti-RBD antibodies and a nearly 50-fold increase in neutralizing activity. According to Nussenzweig, vaccination boosts the memory antibodies that develop after infection, producing an “outstanding response.” "

Keep in mind that this study looked at those who had Covid and then were vaccinated, so your order was reversed in that you were vaccinated and then had Covid. But, it does appear that the combination of getting the vaccine and having recovered from Covid have a synergistic effect in terms of producing far more antibody capability than either event by itself.
I had Covid in June 2020. I donated convalescent plasma often, as the antibodies from recovered Covid patients are used to treat some patients in ICU. Every time I donated they tested my antibodies and reported back to me the findings. Although I was not able to get specific values, they continues to tell me that my antibody levels were high up to 8 months after having Covid, at which point I stopped donating to get ready for valve surgery. Two weeks after surgery I was offered the opportunity to get vaccinated while picking up a prescription at Costco and took it.
Personally, I would get the booster as soon as they tell you that you are eligible. But, having said that, in that you have now been vaccinated and recovered from Covid, I would expect that your antibodies would be sky high right now.
