Nervous

Ma

I took two home pregnancy tests last Thursday when I was six days late and both showed up positive but the lines weren't very strong. Since then I've told my husband and my bosses at work but I just keep worrying what if they were wrong. Is it a possibility? I mean I've felt what I think has been some slight morning sickness and I called my doctor and told her and she just said congratulations and to come in for my appointment at 9 weeks and scheduled it. Am I worrying for nothing or should I test again? I've had no bleeding or spotting.
