I think what you need to sort out is whether your only problem is growth of facial hair or whether there are other underlying medical problems affecting, for example, your fertility.
If there are no problems other than the facial hair you may be best to address the facial hair problem by laser treatment (if your coloring is suitable) or by my own favored method of shaving using a men's electric razor (Norelco in my case).
If there are related problems affecting your fertility, address these first and you may well find that the treatment prescribed for them may help reduce the amount of facial hair.
