I think I'm having the opposite issue: My periods were becoming closer together for the past year. I had a period on Feb. 17 which was the same day when I started my first whole30. I had another one on Day 22 ( i believe) during thwe same round.I still haven't had a period for nearly a month which is unusual for me to say the least. I'm definitely not pregnant, but maybe my initial whole30 fixed my hormonal problems.
