No advice with the symptoms - but my first cycle on keto was horrid. It was just sooooo heavy. I'm a year since that cycle (so 12 - 13 cycles) and my period is so much lighter. Each period since July last year has really improved in symptoms and heaviness of flow. Keep it up ladies, I'm proof it gets easier.
(Back story - my cycles before keto was so revolting. I had to take really strong pain killers, had PMS, went on the Pill to make them lighter)
(Extra tidbit - I learned it was because of my late great uncle the Pill came to Australia! Can you believe it?)
