Has this happened to you??

I’m 15 days late and thats NEVER happened to me and I’m still getting BFN I’m so confused😖 my breast have gotten way bigger and feeling full and heavy my nipples are rock hard and are extremely sensitive and my areolas are super swollen and double the size and are getting darker and they are even leaking. I’ve thrown up I’m always nauseous I’ve passed out and have been really dizzy and I keep getting heartburn which I NEVER get. And I have been peeing WAY more. I have a blood test Monday but I was just wondering if this has happen to anyone else and if so were you pregnant or not??
