Clearblue positive with BOOK ERROR SYMBOL?!!!!


My period is due in 4 days. I took a test the night before last and got a negative, not even a faint line... ive felt off all week so I decided to wait and take another one this morning.

I had to pee like a race horse so I open this digital clearblue rapid response test and it almost instantly says pregnant BUT with this book symbol in the corner. I look in the pamphlet and it says it means there was either too much urine or it was not held in the proper downwards position. But it didn’t say what if it says a result AND the book symbol. I’m obviously freaking out and I cannot get go out to get another test. Has anyone else seen this result?
