Years ago, when I was taking BCPs to prevent pregnancy, I had absolutely no side effects from them. No weight gain, no moodiness, nothing. But now, I have a headache that just won't go away, nausea, weight gain, bloating, the works!
That's what got me thinking of the side effect of the IF business all together. Here is my list so far (in no particular order):
Fatigue, frustration, lack of empathy for other people's problems, obsession over the inner-workings of my body, hypersensitivity, irritability, superstition, minimal sex drive, blotchy skin, loss of self-confidence, ...
Care to add to the list?
