I'm pregnant and af is only one day late

I got upset at first because I'm only 18. I'm only a day late but I just knew I was pregnant. Glow has always been accurate and my period would start on the day it said it would. I just need to know how to tell my mom. Any advice? My breasts are really sore and I'm bloated. I feel a little cramps and tingles from here and there. It's weird because something told me I was pregnant I prayed that my unborn child would be healthy a few nights ago​
