Really confused

Mimi

So today 2/2/2020 I’m either 7/8dpo . Friday I wiped and seen a little speck of blood twice . So I assumed implantation . But then idk . That would have made me either 5/6dpo . Expected ovulation was January 25th . Didn’t feel ovulation cramps until the 26th . Starting on the 28th , I’ve experienced back ache , sore nipples , tender breasts , headaches , mood swings , insomnia, exhaustion , fatigue , extreme craving for cookout burgers and hush puppies . Frequent urination. Mild cramps , hot flashes through the night . Barely can sleep.. wake up first thing in the am and can’t go back to sleep. Bottom line could I possibly be pregnant . I have no one to talk to about this .
