Am I crazy?

Anna

So I'm only 5dpo, but I'm having all sorts of symptoms.. While I know this probably isn't possibly, have any of you ended up being pregnant, when having "symptoms" that early?

Having TEERIBLE lower back ache, headaches, feeling sooo emotional (very unlike me), feeling nauseous at random times throughout the day.

I know I'm probably just wishing too much but hoping for some encouraging stories x
