Is it normal to have a small bit of spotting during ovulation?
It can be. The two causes theorized for this are:
1. This time represents a shift from the first half of your cycle to the second, and the hormonal support for the lining of your uterus may be a little shaky during this transition. This would be the most likely cause, if your spotting happens frequently, and possibly indicates an inadequate luteal phase (your doctor can identify this).
2. The actual ovulation may involve a tearing of your ovarian capsule through a small vein, with blood leaking through the tube out toward the vagina. But, this would be extremely infrequent.
