I didn't experience anything like that but I did have two early miscarriages whilst on it (well actually as soon as I stopped taking it, as you aren't supposed to take it when you are pregnant). Google it and you will find lots of ladies who've had the same problem, you will probably also find lots of ladies who've had the same problems with it as you've had.

I stopped taking it and two cycles later was pregnant again and this one has stuck. I know it doesn't answer your question, but I think there could be a number of problems related to using this particular vitamin.
