Strong positive then super faint positive two days later?

Blind•Melon • 25 years old. Married. Mommy of two girls & one boy.
On Tuesday I got a very faint positive and by Wednesday I got a very strong positive. 
Well all day I've been crying because something doesn't feel right and this is my third pregnancy so I'm not new to this. I've been cramping really bad and don't "feel pregnant" 
So I took another test today and it was barely visible...
Does this mean I'm losing the baby? 😢
