Sooo confused

I could cry I’m so frustrated. I’m still waiting on my blood work but I keep getting bfp tests then negative then faint. Even the digital said no and then a few mins later said yes but had the clock on the screen to. Idk what to do I feel so damn annoyed. I haven’t had a period in over two years and I’m on birth control. I took two tests the other day one was really positive then the other was faint. Then I got a positive this morning but still not dark. The really positive test is not yellow so it has to be a few days old idk
