if it is on the side you o'ed on.. it could be the corpus luteum.. I had that with my bfp.. it was nagging ache..
best of luck to you.
bUBut my "o" pain subsided on Monday and I have not felt anything from Monday Night until Wednesday night. I am soo confused when I look back at last month the horrific pain and almost passing out occured dpo 5 into dpo 6 I am soo confused what could be happening to me?
My o's got pretty bad some months (one time, the ovary area hurt for 3-4 days)...i finally called the RE and they told me that it was just a sign of a good ovulation and not to be worried (I too suffer with ovarian cysts, but they didn't seem to think that was it!) Hopefully it's a good sign that this is your month!!! :)
SSBD to you!
