Help?! Positive or evap line????

OK so Im 22 me and my bf have unprotected sex I'm not on the pill and we had sex during my fertile window twice. Now ever since ovulation I seemed to have all kind of off and on symptoms cramping, smells, nausea, trouble catching my breath, mood swings, peing a lot, tender boobs(sometimes sharp pains and tingeling once), headaches, and just all around feeling blah. I've been thinking maybe it was in my head sometimes, but not today. All weekend I've been feeling sharp pains in my ovaries and in my stomach, pelvic bone and pubic area, especially today. Now I took a test at 6-7dpo with a first response and a 88cent test from walmart, they were negative. I'm currently 10dpo I took another first signal 88cent test with my first morning urine. Now I have never seen a test do this before. I dropped my pee and waited. The first line showed up I waited for it to dry and held it to the light then put it back down. Two minutes after me dropping my pee it started lightly turning pink in the corner like it does when you first put the urine in. Then it started slowly moving up! It was so light though I thought I was tripping so I called my mom in the bathroom and she seen it to! It became a line I think, a thick line. It stayed for a while then started moving again until it went past the second line and disappeared. I examined it a while longer after that and I thought I could see something but I just thought it was the hcg strip. I left it on my dresser then went to my bf's house until like 6pm I came home looked at it and now it has a faint line. Can someone help me out I've been cramping having headaches and just all around feeling bad today!!! Today is Sunday and my AF is due Friday, what do you ladies think?!??
