Positive ovulation test

My fiance and I are trying to get pregnant. I have a 11 1/2 month old already. I just took another ovulation test and it came back that I am ovulating! What are some good tricks to try and make a pregnancy stick!! Is one position better than another? I've heard so many different things but don't know If they are true or not! I also heard that an ovulation test can detect if you are pregnant, is this true? Should I take a pregnancy test and see?
