Labor??? Please help!

Randee • 21, FTM & single mom, to the most beautiful baby girl 🎀👑💕
I'm kinda freaking out... I've been have contractions lasting about a minute, minute & a half coming about 5-7 minutes apart. My belly gets hard, my lower back hurts & it feels like my period is coming on... Am I in labor? Should I go in to L&D?
My doctors office doesn't have an after hours line...
