I'm new at this and going out of my mind. First month trying. 3 weeks into cycle and feel really awful. My back is absolutely killing, have stomach cramps too but the back is the worst. Had some pinky discharge today (TMI sorry!). Know symptoms can be same as AF, wonder am I just being hopeful. What do you ladies think? Also being feeling really hungry lately...like just after a meal! Am I just been too hopeful, how soon do symptoms tend to start?
