Hi LiIlyJ, I also didn’t have my period for a couple of months when I started the diet, so I suppose it’s not unusual. I went to my gyno and she gave me hormonal pills to induce it, so I eventually got it due to these pills. But I wouldn’t recommend these pills to anyone, I felt awful when using them. I heard that Lady’s Mantle tea is great for naturally inducing your period so I’ll try with this if I don’t get it this month (I’m not using these pills anymore). But I would advise you to go to your gyno just that he checks you with an ultrasound to see if everything’s ok and to calm you down.
