I think I might be pregnant

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

I'm 17 and I've been trying to conceive with my fiancé for a month and now that I think I'm pregnant I'm scared af. I've had my period on the same day around the same time since I was 13 years old. And I'm a day late. How long should I wait to take a test?
