trying and trying

hey guys good morning so couple days ago I posted a pic of my pregnancy test that came out positive so this Monday I went to the dr all happy just like any other person that knows they are pregnant so when they took the pregnancy test it came out negative and I was like wait I took 3 pregnancy test at home and they came out positive so what's the next step to know if i am or not and they said blood work and I said okay lets do it so I have to wait until Thursday fml so I don't know what to think I feel pregnant but I just don't know what to think
