I have clear stretchy discharge and my period was due about 5 days ago? using pull out method. could i be preg?

my periods aren't always regular, and the last period i had was 33-34 days ago. i have been using the pull out method and thought i ovulated around 15 days ago, when i had a clear little stretchy discharge. since then my dc has been kind of thin, creamy white until this evening i notice it is clear and very stretchy (something i rarely notice when i ovulate), i have been extremely tired the past week or so, sleeping way more than usual, had headaches, been constipated, with a dull achy lower back ache and on and off "cramps" (not sure if its gas or from constipation or pms). the past few days i also notice myself burping alot, which is unusual; ive been slightly to sometimes very nauseated almost constantly for close to a week, and every time i try and smoke a cigarette i gag. ive also felt overall achy and my nose has been a little congested. so i may just have a bug, the only other thing ive noticed as odd is my vision has been a little blurry. im not sure if im just worried and imagining things or i could be pregnant. im going to get a test soon, but im afraid of the results. my only child is almost 3 and ive been struggling to have the energy to care for her this week. any and all guidance would really help me get a better nights sleep- as long as these crazy dreams stop. please help.
