When do pregnancy symptoms show up?

My husband and I started, finally, to TRY for a family. And all week my lower back has hurt so bad! And I’ve been cramping some also. My period isn’t supposed to start until next week. But my emotions have been off (i.e. easily irritable, wanting to cry, feeling nauseous!)

Am I pregnant?

I haven’t taken a test yet, because I figured it would be too early to tell!
