Is it too late to decrease cost when couple weeks away from wedding?

I am currently about 3 weeks away from my wedding. Just me and my mom are paying for the wedding, FH does not have a good paying job and he did not want a big wedding (He tells me all the time hes sorry that hes unable to help me) . I spoke with my planner and she said my wedding isn't fully at a WOW factor and so I told her to add about $10,000 thinking my previous payments were almost done. We spoke about this almost a month ago, well 3 weeks away from the wedding she sends me the updated budget and it is way more than I thought I could afford which is leading me to anxiety, crying and debating to take out a loan for the wedding (which I do not want to do), and I can't even tell FH how much it is. With that being said would it be too late to tell her to remove some of these stuff after she already contacted the vendors?
