HOSPITAL LIED!!

So I took a pregnancy test a few days ago and it came out postive and I had cramping today after and decided to go to the hospital because I had a miscarriage not that long ago (February) and so I went worried maybe I'm having another miscarriage and first of all I just sat there for 4 hours and all they did was make me take a pregnancy test and I also got a lecture by the doctor about how I should wait till marriage to have children but I honestly don't want to get married yet anyways I took the test and the doctor looked at it and said it was negative and threw it away then continues to tell me to get in birth control immediately so after he left the room I took the test out the trash and it was positive I was furious and just left.
