Am i ovulating or not??

MamathaSumesh
I had my last periods on sep 26th ( i have correct period cycle), and i started using ovulation strip(i sure) since 3 days now but shows negative result. 
​As per doctor ,if mensuration is on proper date then there is no ovulation problem.. And also i tested after 10 days of my period and which shows negative 
​I just want some suggestions about this, either i am ovulating or not??
​ 
​Thnkz in advance!!
