I started taking fish oil a few days ago and since have missed my usually on time menstrual cycle. I have taken a pregnancy test and it came back negative. Is the fish oil to blame?
That's a new one to me so I wonder if something else is going on. I was incredibly regular over the years and yet once in a while my cycle would seem to re-set itself. That's pretty normal. I would also review my exercise - some heavy bouts can delay onset; I will see if there's any literature on fish oil and menstrual cycle and post it in a blog if there is.
