Yesterday night after

I was having so pretty strong cramps. These could be associated with O, but I have never cramped around O before. Then today the same thing... cramps. I'm on CD 10. I have been charting, just not taking temps. It's not time for

to show soon, either. I'm sort of hoping that this is O pains. We aren't yet TTC and the timing wouldn't be quite right, right now.
Also, for the past 3 days I have been having pains in my left side ovary. I have never had the pain like that last for more than an hour. The pain does come and go during the day and is more at night.
