UPDATE

I'm 5 days late according to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">eve</a> and I've got thick white discharge, I'm having the usual period symtoms but I'm really scared I'm pregnant. I've read it could be due to stress because I have my gcse results tomorrow. Please help me in only 16 
Update!! 
My period has arrived!!
