Pregnant or not pregnant

So I normally don't like to post but I'm in the need of some comfort. So I recently took a pregnancy test and I can't tell if it's a yes or no. I was been trying and praying to get pregnant a really long time! My last period was 9-17 of June. So I'm probably gonna wait to test again the 22. I thought I could see a very faint line but again I think it's probably me just wishing it was. So please any advice and prayers would be greatly appreciated.
