Evening Primrose Oil and Folic Acid may not help in the regulation of your hormones but they are good supplements to take for general well-being and folic acid is an important supplement to use for the wellbeing of the foetus if you conceive.
Your body will naturally eliminate excess hormones and regulate itself after a few months. it can however take up to 18 months before normalising completely. I would encourage you to use livotibb, which stimulates the function of the liver to break down and eliminate excess hormones efficiently. You can also use gynaecare syrup.
If you have just gone off the pill, allow your body at least 3 months before trying to conceive
Eat foods that supports your body like fruits and vegetables, nuts, legumes and oily fish
You should also have cupping done on a regular basis. This will facilitate elimination of toxic matter and help stimulate the reproductive organs and the liver
