Baby Shower Superstition? Mom-In-Law

So my mother-in-law asked that I don't plan my Baby shower until after the new year. Well I will be 20 weeks on 11/22/15. New years will put me at about 6.5 months pregnant. I feel like that's too late because number one his family is in another state than mine. We would have to travel. And to be due in April and not even start planning until January is killing me. Is there a superstition? Does the likelihood of miscarriage significantly drop? Should I heed to her request?
