Ovulation signs

I have been off b.c for 5 months now. I just KNOWINGLY had my first positive ovulation test 4 days ago. I went ahead and tested the following 2 days and they, too, seemed positive? For the last 1 or 2 weeks though, I have had minor soreness come and go in my breast. The day before I got the positive opk I started having period-like cramping but my period is not due until the 10th. I had been on b.c since my late teens so I do not know my ovulation signs. Are these typical?
