Faint line disappeared?

Brianna
I took a test this morning, even though I know it's early. Originally I saw a vvfl but then a minute later it disappeared. Has this happened to anyone else? Am I crazy? Am I maybe pregnant? I know I need to wait and test again later but I am just wondering. I get migraines and my meds aren't safe to take if I'm pregnant. I don't want to risk anything.
