Second One, Is It On The Way?

Last Thursday I got myself a pregnancy test pack, it was POSITIVE! I was shocked, and so anxious as I dont really expect this to happen now. Strange that this one is so different than the first one, I dont feel I am pregnant. Well, I am glad that I dont feel morning sickness, I just doubt.. Am I really pregnant?? Can the test pack be wrong?? I know I can just go to see the Obgyn, I just dont feel like. If it is counted from my LMP I am now on my 7 weeks, so I thinks it is still too early to go to see the doctor, maybe in a few week. Maybe it is just a wishful thinking of not being pregnant, maybe I am not really ready to have another child. Little info: Weight: 87kg super obese!! i know :(
