High fever

With thrush? DD (and myself) have had thrush since at least Monday, we started treatment on Wednesday (because the batch nurse argued and told me it was HFM ?). The thrush has been noticeably better in her mouth, the white "ulcers" are gone and her tongue is no longer white but this morning she woke up an hour and a half later than usual and when she got up I noticed she was HOT so we laid down in bed for about 20 minutes nursing and such (with no blankets on) and we came downstairs and I checked her temperature and it's at 102.6! That can't be from thrush can it? I know, you're not doctors, I'm giving the Motrin 1 hour to drop the fever and I'm taking her in.
