So this is my question can you ovulated just 5 days before AF arrives?,
The thing is, you can, but if your luteal phase (the time between O and AF) is any less than 10 days, then it is a sign of something called luteal phase defect, and it is not good, as your luteal phase has to be at least 10 days to sustain a pregnancy. I would not panic though, you might have just got your temps wrong, but, perhaps, for piece of mind, you may want to talk to your doctor? They can test for that, I got tested after my M/C. Basically they just check your progesterone levels afer you O and the thickness of uterine lining (this is one unpleasant test). I really do not want to be negative, but if you really have this problem it is better to know, as it is fixable, I think they just give you progesterone injections.
