On off symptoms

I'm almost 11dpo. On and off during the day I convince myself I'm definitely pregnant because I FEEL it. I feel heavy, a bit crampy, this morning I feel nauseous. But then at other points in the day I feel totally normal. I have already 1 baby and I remember what it felt like so thats how sometimes I feel.

Anyone else had this and gone on to be pregnant? I know its early but getting disheartened.
