Help - TMI

I've been taking a pregnancy test every morning since I found out and I'm 6 weeks and 2 days today. This morning when I did my test I used a different looking type of Internet cheapie and the control line is a lot lighter than I'm used to. I also had a slight amount of discharge that I haven't had before. I'm freaking out because I had some pain in my left side when I got out of bed this morning too that I didn't think much of at the time. Am I losing my baby? I'm feeling scared and alone - my partner is away camping. Please help me.
