clear blue opk

I'm confused, I'm using clear blue digital advance ovulation test and I've been testing for 12 days now. I've gotten the flashing smiley "high" fertility for 10 days straight now with no solid "peak" smiley. I stopped taking my birth control on 12/25/16 (finished a pack and didn't start a new one) and had a short period 1/31/17-2/3/17. I'm thinking my cycles haven't regualated yet since being off the pill? Not sure if I should keep testing or just start again next month. Any advice is appreciated 😁
