3 day, light period and BFN. So my AF arrived on 11DPO which is is normal timing for me with my short Luteal Phase. She arrived with medium flow the first day then just dropped off to super light the last two days, hardly any blood for the day in my pad. My period usually lasts for 6 or 7 days and is much heavier. I took a pregnancy test on the 4th morning after she arrived but BFN. Has anyone ever experienced such a random weird AF?
