Frozen eggs

Frozen eggs.
My husband and i did ivf last year after 2 years ttc our second bub and we now have a beautiful 5 month old.
We just recieved an invoice to continue to keep our 4 other eggs in storage for another year.
My husband is adamant he doesnt want anymore kids and im probably 99%sure. Both my pregnancies have been hard and ive had two ceasars with the second one being worse then the first.
But i have beautiful boys and would of loved a girl. Im Unsure if we keep the eggs frozen for another year or two or decide definitely no more kids and not continue with freezing them.
Its 750 to freeze for another year which is a hell of alot cheaper then the 15k it cost for ivf.
What would you do ???
