3dpo according to glow

So we did well tracking ovulation this month. opKs, temping and CM tracking. I know that 6dpo is normal for implantation right? Is it possible that you just feel pregnant and you are? I did with my second kid. I totally feel like I am. I have been peeing like crazy today, even had to pee twice in the middle of the night last night. The smell of sausage this morning totally grossed me out. I am having some slight cramping. Am I imagining the feeling or is it maybe really there? We have been trying for 4 months now. Not once did I ever feel prego.
