Are these early signs of pregnancy or am I just going crazy?

I'm not planning a baby at all, actually. But here lately, like the past 2 weeks, I have noticed one major thing, I've had a lot of thick white discharge. No odor. I've also noticed random cramping in my ovaries, but no period. (Although I'm not late for my period, it's not time for it yet. It comes in a week and a half) also, in the middle of the night, I will wake up feeling like I need to throw up! But I just go back to sleep and when I wake up I'm fine. I've also been going to the "bathroom" (if you know what I mean) at least 2-3 times a day! Which is SO unusual for me! And lastly, I'm ALWAYS dizzy. If I slightly bend over and raise back up, I'll be dizzy. If I stand too long, I'll start to get dizzy. If I sit down and stand up, I'll get dizzy. Like everything makes me dizzy! Is this signs of pregnancy do you think? I've never had kids before so I'm not sure what to expect! Haha
