Hi, My Wife And I Are Trying To Conceive. She

Hi, my wife and I are trying to conceive. She has some form of infection near her nails in her foot. These were previously treated using Mupirocin 2% oinment. She wants to use it again, is it safe for early pregnancy days or during the time to conceive? is Mupirocin 2% ointment is the treatment for the kind of issue she is having on the nails? I have attached a photo of the nail with this ticket.
