pregnancy test/period

so my period was 3 days late so i decided to do a pregnancy test and it came back as a positive so i went to the doctors and he told me that it was a positive and said that it looks like i’ll be very early so he made me get a blood test and i should be getting the results back this afternoon, but yesterday at lunch time i started bleeding so i’m so confused. if anyone experienced this before can you please tell me your experience? xxx
