TTC general questions!

Nicole
Hello all! I'm getting so frustrated while trying to conceive. We decided it was a good idea to just try without doing any type of ovulation tests or anything but after 6 months of no baby, we decided to go ahead and test last month. I got just the cheap paper ones from CVS which I believe said we were ovulating on halloween. And we had tried the two days before as well as that day and the day after so I was so sure we would be but today I unfortunately got another negative test...
Are there ovulation tests you love?
Are there ways to promote ovulating?
Do you think you can trick yourself into having pregnancy symptoms? This past two weeks, I have had extremely sore boobs and have been nauseous off and on. :/
