please help

on cycle day 34. my period is late by 4 days. i havent had a cycle longer then 18 days since november of 2017, the month after i had my last child. I've been having a creamy white discharge today and my breats have been very tender. my eating is on and off. i am not on birth control nor have I been since december of 2017. i do not use condoms when i have sex nor does my husband pull out. I also just moved 500 miles. my husbands grand father just passed away. where im living isnt a very good place. my mail hasnt shown up yet and i am waiting on a last paycheck from my old job. im not sure if my period is late because of stress or if i could be pregnant. i havent tested yetz because im broke until i get my last check. what do you ladies think it is. im just confused. I went from 18 day cycles to a 34 day cycle. I've also been getting some slight pain in my pelvic area but ive been contributing that to my pelvic congestion syndrome
