Maybe?

So ladies I'm 7 dpo (cycle period 21 days) and I have had extreme tiredness, mild cramping, itchy and tender breasts. I'm to early to test as I fell pregnant with my first 5 years ago I don't remember much about it or never had symptoms. Hubby said my breasts were really big and that's how I found out! Am I making it up in my head or could I be pregnant? What symptoms did you have? Thanks 😊
