I was on birth control starting at the age of 17 due to very heavy periods. I went off them after college to give my body a rest and then went back on them for 2 years. I stopped taking them about 3 months before I got sick because I didn't like the idea of taking a pill everyday. I find this amusing becuase I now take 20 a day now!! Anyway, I noticed that my fluish fever cycles start right after my ovulation period. My fever cycle will then last 10 days...followed by my period two days after that. All of my drs. checked into the hormonal thing and I can see if my temp was just raised a little during ovulation but it happens afterwards and it is more then just a raised temp. I believe hormones play a part in cfs but now that I am on pregnenlone my ovulation got pushed back and so did my fever cycle. Everything is like 11 days off. I am now wondering if I should go back on the pill for a couple of months and see if I feel any better. I mean I would not be ovulating and then maybe these fever cycles would stop. Of couse this would not fix my problem just mask it but then maybe I could find the reason for my flu-like cycles. Anyone have any insight or this wishful thinking on my part?
