How possible??

Angie • Married have a daughter who was born on 12/12/12, now pregnant with baby #2!! :D
AF due today and nothing came yet.. I took a test on Saturday and it was BFN.. But I am looking at the same test I took from Saturday this morning and it looks like BFP. :/. After I saw the negative I didn't wait very long to see if it changed.. And something this morning (maybe my heartburn lol) told me to re look at the test i took Saturday morning.. Please comment and let me know what you think.. Planning on buying another yet tonight.. ?✨? baby dust too all who is TTC.
