Ive been TTC for a couple months now. My periods have been soo irregular.Cycles have been 28,26, and 13 days. On Saturday (CD14) I had spotting and then CD15 I have enough spotting that I had to wear a panty liner but nothing much. My periods are normally heavy soo it doesn't seem like a period. Nothing so far today (CD16). Any idea if its period irregularity or maaaaybe implantation?????
