Women often wonder if they should stop doing HCG drops during menstruation, here is what we know; HCG is created naturally, so women actually have an advantage. But there is no need to postpone; anyone can start the drops whenever you want to! Many hcg dieters continued using it, however, if there is heavy bleeding you should stop and wait till TOM leaves.
Dr. Simeons original protocol states you should stop injections during your cycle but continue consuming the 500 calorie hCG diet foods. When your cycle is over you can resume taking your hCG and continue with the 500 calorie diet. Dr. Simeons also states to start the hCG diet after the last day of your period. Since women produce hcg during TOM, many have continued taking the drops and found that they still lose pounds and inches.
If you are taking drops, you can start the drops anytime, if you are doing shots then you need to wait until 3 days after your period.
