Nope! Try not to worry!! Make sure you are reading them the right way which is however the instructions that came with told you. If you let a pregnancy test sit, for example, after the time has passed that the instructions say to read the result, a second line can form that is an evaporation line. But if you followed directions and got two positives, that's great news!! You are pregnant. TRY not to worry. I know I was super afraid of miscarriage but nature will take course here and things should be fine. You won't get many symptoms right away and they normally really start around 6 weeks after conception. Congrats!
