I started very lightly spotting Tuesday at 2 DPO, and am still very lightly spotting today at 4 DPO. It is a tiny amount, but I'm still analyzing and trying to figure out what it is from. At 2 DPO I thought maybe ovulation spotting, but I doubt that would continue for 3 days, even if it is super light. The only other thing I can think of is that I took Alieve Sunday night and Monday night and a super strength ibuprofen on Tuesday night for back pain. I know that Alieve and ibuprofen are not good during pregnancy, but thought I was OK since there is no way that anything could have implanted yet. Has anyone heard of either of these drugs causing spotting? Or have any other ideas of why I could be spotting this early?
