is it possible?

Kassidy • I'm 17. Me and my boyfriend are currently trying to conceive. We both so excited about having a baby and are both financially stable. We're super excited. So yeah
Is it possible to to be 3 to 4 weeks pregnant and the pregnancy test not show up? Bc I'm experiencing a lot of the symptoms you get at 3 to 4 weeks pregnant. I have terrible morning sickness and I just can't even stand the smell of cooking meat. Help
