Negotiating an offer, is it too late? - 2 months and counting

It is the first offer in 2 months and I do not want to mess it up. This is my first time dealing with any of this. The benefits are decent. Did it backfire?

Ask about the range, not a number on its own. It felt more collaborative.

Thanks for writing this out. I went through something close to it 2 months ago, and it got easier once I kept a simple log of every call and form.
