HCG Diet

Hello,

I started the HCG (drops) not injection diet on July 16 and continued until August 7th. In July i did receive my monthly cycle on time. I stopped the drops on August 7th because i started to feel weak and sick on the diet. I did lose 10 pounds in 3 weeks. My monthly cycle was due on August 20th but never showed up. I took a HPT and the result was negative. I thought maybe the drops throw my cycle off but after speaking with the company i bought the drops from they stated the drops are out of your system within 72 hours. Could my cycle be screwed up because of the weight loss

Thanks!
