Confused, Help Me

5dpo I was nauseous, headache, bloating, cramps and did have a lil bit of bleeding but only when I wiped and then a lil bit the next day but was a little brown. Since 7dpo I’ve had no symptoms at all. Today 10dpo a lil bit of diarrhea, slight headache, and cramping. Period coming or what? Period suppose to start in 4 days(8/17). Really don’t want to have a baby until next year.
