Questioning my results...

Taylor • Engaged to my high school sweetheart❤️ Expecting baby #1🤗

Last night I decided to take a pregnancy test because my period had been late. Taking the first test there was a faint plus sign, so I took another test but this time it was a digital. That also came up positive. Following the great news I went to the doctors to confirm and I took a urine test and a blood test, both came back negative. I’m not sure what is going on, if anyone has any ideas or advice please let me know!
