This is my first month using soy. And I am curious, did anyone notice a longer period when using it? I don't remember reading that as a side effect. I am usually a long bleeder anyway. I generally have seven days from start (which is heavy immediately, no spotting here) and then by day five it is lighter and by day seven, it is that

brownish end blood, just spots.
But here I am today, on a full day seven (since my period started in the AM) and I am bleeding like no other. Just like day 1-2-3-4. And I am irritable, which I did expect (since I have heard that before). Tonight is my last night on it (days 3-7), so I hope that my period stops soon. But I just wondered if anyone had experienced that before?
Thanks in advance.
