Hey!
No it doesn't have any side affects. I mean of course you are going from a high calorie to a low calorie so you may get a headache the first day or so, but besides that, no side effects what so ever.I am also on birth control and it does not affect it at all. Many times this is supervised by a dr. but you can do it on your own, which is what I am doing. If you youtube hcg results you will see the true results of people.
