Lots of questions

Cassie
Hello ladies, 
​So this morning I took 3 pregnancy tests and all of them came positive, I am super excited, this is the first time that I have been pregnant so have lots of questions, so clear blue says I am 1-2 weeks, however when I got the pregnancy application the asked me for my last cycle and according to that app I am 5 weeks pregnant, bug how can that be possible? 
​Also I called my doctor to schedule an appointment and she isn't available until October 14th!! So is there any other place that I can go for a blood test just to make sure everything is right? And could a blood test say how fat along and die date? 
​Thank you ladies!!!
