I had my last period from Feb. 12-18, and have had some light spotting (brown/red) from Feb. 23-25 (started about 5 days after my period ended). I haven't had sex, and although I've been sexual active in other ways there hasn't been any close contact since at least Feb. 9 (so I think that rules out possibly pregnancy/implantation bleeding, especially with a full normal period occuring since then). I know sometimes ovulation can cause bleeding and I've noticed spotting between periods before, but this time has been lasting on and off a few days and seems slightly heavier (still very light, just more noticeable). Does it still sounds like it is likely to be from ovulation? Any other ideas?
