Moving advice

I just returned to teaching fourth grade after taking off 8 weeks for maternity leave for the birth of my twins. My husband has gotten a job offer in another state where he can start working in march and make enough so that I won't have to work anymore. Should I quit now (school district requires 30 days' notice) or work until spring break and quit? Or stay until May and be without my husband for two months? What would you do?
