I am very sorry to hear that, I know you must be very anxious to get the interview over with, hang in there.

My experience is a little different since it is from the summer of 2019 but I will share. We had to request a reschedule for my combo I-751 (Removal of Conditions) and N-400 (Application for Naturalization) appointment due to my due date being too close to the scheduled date.

They rescheduled me for 2.5 months later. I used that time to prepare even more for the interviews. Before I knew it, the interview day arrived.

I guess it varies, I hope you hear back very soon from them.
