First at that wait I would not be overly concerned, while female rarely do go off feed, exceptions do happen. I have been fortunate that any females I have ever had past and present have always been eating year round well except when being cooled.
Remember like many other species they are sensitive to temperature drops and low pressure.
The things I would try to do is get the temp up on the cool side over 80 if you can, aside from that it’s gonna be a matter of patience.
