I have had a 35 day cycle the last two periods. This month on the 18 day of my cycle I started to spot only when I wiped. I think it just happened once it was red blood mixed with cervical mucus. The next day I spotted again this time brown. The day after that nothing then the day after that more spotting pink and brown but only when I wiped. This spotting comes and goes but has lasted now for six days. Also yesterday after I urinated there were five small blood clots about the size of a pencil eraser. My period is still 11 days away unless I ovulated earlier then I thought and my cycle is shorter this month. Does this sound like implantation bleeding? Or does it just sound like ovulation spotting? We have been trying to have a baby for a while now but I think it's still too early for a pregnancy test. Any advice would really help- thanks
