My husband and I have just started TTC. I have been tracking my cycle with glow while being on the pill and since I've stopped taking it (which was at the end of a cycle). I stopped taking my BC mid July and haven't gotten my period since and have taken a couple pregnancy tests which have been negative. Per my doctors recommendation, I have started taking prenatal vitamins to prepare my body should I become pregnant. Should I be concerned that I haven't gotten my period yet? Could the vitamins have any effect on my cycle? Just wondering if I should contact my doctor or just wait and see. Trying not to be overly worried! Thanks for any help!
