To test or not to test?

I missed my last period about 13 days ago now. I tested and got a negative but I think I tested to soon. I was supposed to get my period on the 5th and tested two days after it was supposed to end. I did have what I believe may have been spotting or implantation bleeding. And I had sex around the time I was supposed to ovulate and have been experiencing, headaches, mild nausea and constipation. My periods are regular and I haven't missed a period in two years. I've never been pregnant before and would love to have a baby but do not want to get to attached to the idea of having one and not be pregnant as I have tried for two years with no luck. I'm completely freaking out and do not want to over think it but I'm trying so hard to wait a littler longer. So what do you all think, should I test again or wait for AF?
