False Positives

How likely is it is it for me to get three false positives?? I took a test on the 22, 23, 24 and they all came back positive but today I took one before I was going to call the doctors office and it came back negative?? What do you lady’s think is going on?? I’m really upset I told my family as part of their Christmas presents and I really hope It was just a fluke today!!

I haven’t had any bleeding or cramping. And have still been just a nauseous as I have been
