Offer arrived, can I still ask for more? - 4 months and counting

It is the first offer in 4 months and I do not want to mess it up. Thank you in advance. The benefits are decent.

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

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.
