FINALLY A.... negative????

I have been opk testing from the day I got off AF (January 20th). I have gotten a positive every single day almost. I was getting discouraged. Today I tested around 12, noon, and got a positive with my cheap dip in urine strips. Then again at 4:30pm I tested but this time with a Clearblue Advanced and..... NOTHING. A empty circle. I’m relieved, but should I be? Does this mean that I ovulated? Af is due again February 11th. I was having strange pains in my lower right abdominal area two days ago and last night I had the same “tugging” feeling in my lower left abdomen. Do you this this was ovulation? Thanks in advance!!! By the way I posted my OPKs below for reference. BABY DUST TO ALL!!
