Really?

My sister who is halfway through her second pregnancy finally asked about my pregnancy yesterday when I was exactly 7 weeks. Her messages started out with are you sure you are pregnant. Hmmm 5 positive home tests, morning sickness, exhaustion, tender breasts, +21 day overdue period yeah I think I'm pregnant. Then she asks well did you get the doctor to confirm it with a blood test. Um, yeah, day after the positive tests. Then she responds don't worry it could just be a false or ectopic pregnancy. Really, I am not bleeding I have no weird or extreme symptoms and my doctor says that the baby and I are both normal and healthy.
