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 approximately 4 days, which never turned in to a real flow with red color. Today (21/7) is 58th day of my cycle and I am 24 days late. I took seven home pregnancy tests (on cycle day 41,50,51,56 and 57) and they all came back negative. What do i do now? Can I be pregnant despite having 7 tests or is it just Ella's side effect?
