1. Well, many times HCG can extend the length of your menstrual period. But, it’s extremely hard to define as the results vary from person to person.
2. Secondly, it is recommended that you are not supposed to take the HCG injections while being on the menstrual cycle. Why because? the high level of progesterone in the women’s body during her menstrual cycle prevents the HCG from giving the appropriate weight loss results. Hence, it is strictly advised that diet can be taken during menstruation. But injections must be taken immediately after her period. Otherwise, it can lead to extreme hunger in the person… 🙂
