POSSIBLE side effects from 2 day diet japan lingzhi???

Ok so ive heard soo many great weight loss with the 2 day diet. I just had a baby a year ago and been trying so hard to get rid of the pounds but instead gain much more!! My mom was the one who actually told me about them and at first i had doubts about them. She then lost 3 pants size in 2 and 1/2 months. I decided to try it and bought my bottle on ebay from 911health. In one month i lost 10 lbs But then i noticed that i didnt get my period.At first i thought maybe i was pregnant. I took two tests, one in the morning and then the next morning before i took the pills. Both said not pregnant.
My Question is, is it possible that the pills could have made me miss my period? should i stop taking them and go to the doctor to make sure? And has this happen to anyone else? Any help or advice would help!

If you are eating alot less than normal it may be messing with your cycle. That happened to me in college, I was really stressed and was barely eating and I stoped getting mine. I would probably go to the doctor to be sure, don't risk your reproductive health.
