Faint line that dissapears


I'm currently on day 45 of my cycle. I've never had regular cycles but even for me this is rare.

I've taken a bunch of pregnancy tests and ovulation tests to try to figure out what's going on.

I just got a new OBGYN who told me to call him if I got to 60 days without a period.

Today I took a pregnancy test and started brushing my teeth. I saw a faint pink line! But it soon disappeared.

I can't handle the stress of am I? Am I not?
