I'm falling apart

I feel like I'm falling apart 😫. Last month, my body gave me all the symptoms of being pregnant down to morning sickness. Now, this month, I'm 13 dpo, and my breast hurt, I've been having cramps since 10dpo, and I was nauseous on 11dpo, on 10dpo. I got dizzy and the same with 11dpo. I don't ever have any of these symptoms when my period comes. I actually don't ever know when it comes. I've already taken two tests, and they both came back negative. I'm really wanting to be pregnant, but I'm starting to wonder if my body isn't playing a trick on me again like last month 😭 anyone go through the same thing?
