Baby shower dilemma

So, originally my mom was planning my shower and we were going to do it March 13th. Then my aunt a few weeks ago insisted she do it and we agreed and thanked her for even offering to host it. Since she has taken on the task she has been hard to communicate with. I sent her my address list and guest list almost three weeks ago and her response was she may move it back one weekend and make it March 20th. So today I text her and said "Hey, sorry to bug you, but did you ever decide which weekend would work better for you?"  She finally text me back and said April 3rd. Which is the weekend I'm moving. So then she said the only other weekend we could do would be April 17th which puts me at almost 38 weeks. I really don't want to be doing that so soon to my due date. What should I do???
