I didn't get my cycle back until ds was 2.5, so 30 months. I bougth it back by not nursing for 5 hours straight a night. I also ended up getting accupuncture and my accupuncturist told me that my body was so depleted by ds that I didn't have the energy or nutrition to support AF needless to say another baby. So i started eating blood and 'chi' supporting foods, did Moxa, and received accupuncture 1-2times a month and then I started having regular healthy cycles.
At 5 months, i wouldn't worry and if nursing on demand I would't expect or desire AF to return until about 14 months.
