I've Been Trying To Get Pregnant For The Past 8

I've been trying to get pregnant for the past 8 months. I just recently bought a fertility test from ClearBlue and on the 12th it gave me a smiley face!! My husband and I had intercourse the night before and the day after it gave me a smiley face. but on the 13th I took another test in the morning and it just gave me a circle. (saying that I wasn't ovulating. Does this mean that im done ovulating and that I cant be pregnant?
