Omg I think I'm finally pregnant

My af is due the 8th or the 9th. I've been feeling nauseous. I threw up brushing my teeth. My boobs hurt and feel really full I know my boobs so this definitely has to be pregnancy. I was really depressed last week for no reason. I have wet slippery cm which is usually dry by now. I've had lower back aches which I never have. I had some weird pain down there that reminded me of when I was pregnant with my daughter. Any input would be nice. I'm going to take one of those early tests. Wish me luck. I'm like 97% sure I am.
