A little confused 😩

Kymia
Just recently I took a pregnancy last week, 3 days before my missed period. It came out negative now AF is late, she's never late, she's usually on time. So she's 3 days late. The problem I'm having is I can't tell the difference between PMS symptoms to Pregnancy symptoms. 
• I have really bad gas
• I'm hungry like 8 times out of the day 
• my boobs have not gotten big, but my they were sore and a little tender
• Everytime I feel something coming out of my vagina, it's not blood it's white creamy fluid. (This been going on for about a week now) 
• I have weird cravings of food I would never even eat in my life. 
• im extremely tired (but im also anemic so it also affect my body temperature too)
• light headaches
• I gain a little bit of weight. 
Those are all my symptoms. I have no nausea or vomiting. Or no light bleeding. 
This will be my first child if I am pregnant. Im patiently waiting to see if AF comes, I don't want to waste more money on tests. What are the symptoms some of you women have when you was first pregnant?
