False Alarm😡😥

Mrs.M

Took a digital pregnancy test on December 30th and it was positive (was in total shook) so the next morning I took another one but it was negative (now I’m confused) called my doctor and she wanted me to go do blood work ( was keeping my fingers cross that it’ll be positive) it came back NEGATIVE ,how can this be? I have never heard of a false positive,so sad and frustrated.TTC is such a emotional roller coaster
