Am I pregnant?

Okay so I've had a lot of symptoms and my period is now 2 days late. It is like NEVER late, it's either early or on time. I'm 15DPO. My symptoms are: boobs really sore, like SO sore. They feel almost bruised and full/heavy. Sharp pains in lower back come and go. I've been extremely tired. Yesterday and the day before I slept in till 3 in the afternoon, I usually wake up early. Today I woke up at 10am but went to sleep at 5pm and have just woken up, it's 1am here in New Zealand. I've had cold like symptoms for the last week, runny nose, sneezing, headaches, a temperature that is either high or low, been getting really hot then I'm like freezing. My CM is white, creamy and slippery. I've just noticed it yesterday. I never really get this stuff. I don't have any cramping or stomach pain though. I've been feeling really moody. Emotional!! My partners been making me cry over the smallest things haha. I've been really thirsty, I usually drink 1 or 2 drinks the whole day, lately I've been having to drink all day. Been peeing a lot more too from drinking so much. Appetite has increased so much!!! Usually don't eat much, I would skip breakfast and maybe have lunch or dinner. I now have to eat pretty much all throughout the day. My nose is super sensitive, I was in my bedroom for about 5 hours sleeping, went in the lounge and started sneezing straight away, must have been from the cat hair, but I'm not allergic? So those are all of my symptoms. Anybody been similar? I am going to take a test in the morning :) wish me luck!
