I'm in the same boat as you. I'm 17 also and me & my boyfriend want a baby. It's just in the last couple of days we've decided though. Currently we're having a pregnancy scare and it's turned into a want, and not a scare.
I haven't come on my period yet but I don't think I'm pregnant yet so I'm just waitin to come on

. I've been with my boyfriend 2 and a half years at the end of October.
