Hi DJTTC,
Try not to stress too much - it might be good news - implantation bleed?? Dr's like at least a 10-12 day luteal phase, so if yours is at least 12 days, you have nothing to worry about. I have just started Vitamin B6 to try to lengthen mine, apparently this works...there is also a progesterone cream which is the next step I am told...keep us posted.
