I'm in a situation similar to yours, EndlessDestiny. Three days ago, an agent who's read my full offered to send me her notes. Some time after sending her my full, I started a list of tweaks that I want to make to my manuscript, but I haven't made them yet.
I haven't received the agent's notes yet, and I know it's WAY too early for me to nudge. But in your case, I agree that you should probably wait at least three months before nudging. My guess is that this agent is currently busy with some client work, or is re-reading through your manuscript so they can make note of everything they think you should revise.
I don't think you should email the agent about having made revisions. I think you should just wait until she emails you her notes, apply whatever changes you agree with, and send your revised manuscript back to her. Then you can mention to her that you've made some revisions of your own (if you want, but I don't think you have to since I'm sure she'll notice them). I plan on only mentioning the changes I make on my own if they're (1) major revisions and/or (2) oppose a change that she suggested.
Congrats on making it this far! And good luck!
