i have been cleansing my candida for one year and three months. when my body is going through an intense clease, it throws off my endocrine system and progesterone (which causes ovulation and eventually, menstruation) is not produced in the correct amounts.....this causes my menstual cycle to become very long and drawn out. i have had 59 day cycles at my longest, and when my body rests for a while from cleansing, i have regular 28 day cycles. often during the long cycles, i did not even ovulate.....as if my body knew that it was not a good time. i, personally, have always found pregnancy tests to be very accurate, but you might want to wait a week and try one again.
as for your cycle....as your body cleases, it will become more and more normal. make sure you find a good acupunturist to work with you in regard to the cleansing and your cycle. this has helped me sooooo much.
just to warn you.....you may find that on your long cycles, the pms is much worse, too. it helps to rest a lot and to eat no carbs (if you can stand it).
get the book 'the body ecology diet' if you want to beat the yeast once and for all. i started it this month along with primal defense and my body is healing rapidly. good luck.......tif
