Nighttime potty training is a misnomer, there's truly no such thing. When her bladder is strong enough to hold it all night until morning she will. Limiting fluids doesn't help, or waking her and taking her in the middle of the night. My granddaughter's pediatrician said they don't consider it a problem at all until at least 8 years, but even longer can be "normal." She was about 7 when she started staying dry through the night.

ETA - Lol, if she's waking you up every 5 minutes, have you told her she doesn't need you to go and can go on her own? Provide nightlights to light her way there, practice in the evening before bed, first with lights on, then just the nightlights. My guy has been doing this since before 2.5 so I'm thinking she should be fine.
