How long are your cycles? What I read in that hormone book, was that if your cycle was running short, you should take the days off the beginning, so yes, you could ovulate early. That would make the most sense if your cycles were about 3 weeks apart?
How are you doing otherwise? I talked to my nutritionist about the candida/ibs-he is actually looking into it himself and thinks the probiotics and no Sugar are a good way to start. Have you noticed a difference with the IBS since you are drinking the kafir?
