Early symptoms or flu.

Have any of you have early symptoms that felt like the flu? For the past week I've felt very off, almost like I'm getting the flu but it never comes. I've been nauseous but able to eat only certain foods, completely exhausted, my boobs have felt very heavy, and SUPER bloated. Aunt Flo is a couple days late but I'm not stressing out about it. I'm just wondering if any one else has had flu like symptoms and still got their BFP.
