I recently started taking Vit C an realized that is had splenda in it. I stopped taking it and ordered the Nature's Sunshine Vitamin C - Citrus Bioflavonoids and am waiting for it to arrive... Anyway my question is: My last period was about 2 weeks ago (at the most) and I have already started my period again. Could this just be a symptom from the mercury or could the splenda have caused it? I have never been irregular like this (also I am not on birth control either-hate the stuff)
