I took Ella 3-4 hours after I had UPS on 11/6 which was predicted as my ovulation day by app. On the 2/7 I had a brown spotting with clots and tissues that lasted apx 4 days, which never turned in to a real flow with red color. Today (16/7) is 53rd day of my cycle and I am 19 days late. I took 5 HPT (in cycle day 41 and 51) and they all came back negative. What should I do now? Is the spotting normal or can I be pregnant?
