Opk testing

Hubby and I took a break from tracking and ttcing after trying for 4 years and 2 miscarriages. I decided this month to start back taking prenatal vitamins and opks. This past Saturday I got a positive on my opk but decided to continue to test. I got another positive yesterday and this morning as well. I only continued to test because in the past I would get a positive and stop testing and stop baby dancing for a few days with nothing happening. Anyone else get a positive opk for days in a row ?
