Does it sound like i ovulated either overnight or today?

Today i am on cycle day 18. First round of clomid 100mgs I took days 3-7 on October 20th through October 24th. This past week I have been crampy. Last night I was feeling dull pains on both sides. Is that ovulation pain? Does it look like I ovulated over night? I just took another opk and it was low negative. I have been having creamy cm today.
