Welcome to the forum Kathryn.
No no need to worry. It is quite common for these snakes to go on a hunger strike, usually during winter months and at breeding age.
My female adult is like clockwork every year, September/October through April/May.
Many folks with hunger striking snakes have said that their snakes usually start eating around Easter.
Hunger strikes can go longer or shorter.
As long as your snake does not look physically underfed by being triangle shaped with the spine showing starkly, then no worries.
Theses snakes are a marvel at maintaining their food intake over a course of a year roughly, because most captive Ball Pythons are overfed.
Here is a picture of Elvira. She has not eaten in 5.5 months. She doesn't look thin at all.
She is under the heat lamp after spending 4-5 days on the cool side and ambient areas.
I also previously poured water in that spot to maintain humidity. Maybe she likes the cool and warm combined or "fresh" humidity?
