Is it possible to have a double ovulation? I had a positive OPK late last week and we BD'ed four days in a row afterward. But, my temp stayed low. Then yesterday, I starting having some cramping, and fertile cm, and then my temp spiked. And I have had cramping since then, and my temp has stayed up. I took another OPK and it was a solid line, but not darker than the control but darker than I would expect it to be.
