i've been taking prenatal vitamins and at first i had diarrhea becuase of the laxative it them but now its kinda normal, almost constipated even, and im still taking them and havent ever missed one so im just curious, could this mean im pregnant? I also have been for about 6 days now have had sore breasts, back aches, fatigue, acid refulx, and bloating. I have 23 day cycles regularly & now im about 3 days from my due period.
