I've been ttc #2 since may, ended up taking clomid to conceive #1. My cycles have always been 35 days but the past 2 have been 49 days. I'm now on cd25 with very light spotting. I have no idea when or if I've ovulated, could this be implantation bleeding or ovulation bleeding? If not what could it be I've never spotted in between periods before. Tia
