Really stupid question, but…

Has anyone ever FELT pregnant, like couldn’t put their finger on it, had a negative test, but then actually been pregnant? If that makes sense.

Like, all today, I’ve felt exactly how I felt when I first got pregnant with my first two kids. I can’t put my finger on it. I just feel like I’m pregnant. But my test is negative. So maybe I’m just going crazy. Lol. I’m 8dpo.
