Aldactone and headaches

I'm taking Aldactone for PCOS and was exhausted with terrible headaches for the first few months. I have taken this medication on 2 different occasions so I had to forced myself to stick it out because it does work but getting used to it was the tough part. After the first few months my body adjusted and all was well minus breast distention and occasional tiredness.

I've only been on it for just over a week, taking 25mg daily x 7 days and now !00mg daily. I am experiencing mild stomach cramping but nothing else. Have not seen any improvements yet either. I am menopausal, so I can't gage my periods. My facial acne developed when I became pre-menopausal at around age 45. I am now 52. I sometimes get very slight headaches if I don't take the medication on a full stomach.
