I just want to be pregnant!!

My SO and I have been trying to conceive for almost 2 weeks now and I just want to know when I should take a test and is there any positions that can help the sperm reach its destination faster and more efficiently?? I was so anxious I already took a test and it said no but I haven't had a period since August 3rd, but I also quit taking birth control so I have no idea what's up with my body!
