Does Double Dose Of HCG Diet (injection Form) Affect Health?

Just started the HCG diet (injection form) and misunderstood the frequency and amount to inject each day. I injected twice instead of once. Just realized today and am now on the 3rd day of the protocol. I am very concerned what I may have done. I will obviously not inject again for 24 full hours but is there anything else I need to do?
