CAN I STILL GET PREGNANT?

Kavitha
On November 14, 2015 I was ovulating & November 16, 2015 too. These 2 day's I was ovulating. On November 15, 2015 I check if I was ovulating but my ovulation kit said no. So my question to everyone is can I still get pregnant? Also when should I check if for the pregnancy text? I have irregular periods. What should I do?
