1st month TTC and I have a “noob” question

Jenna • Kennedy 07/2020

I love the photos that I see ladies post of all of their preg tests lined up where you can see the line progression over several days. But I guess I thought that when a test sits for a while it can change the reading, so how accurate are the line progression pictures?

I took a test yesterday and it was negative but in the trash can today it was positive. A faint positive line.

What does this mean for me??? 😬
