6dpo and all of this going on

Wow I don’t know what to think, but I know it’s way too early for this symptoms:

• nauseas

•low back pain

• sensitive to smell

• dizzy spells

• cramps like crazy

• weird feeling in my breast

• waking up randomly in the middle of the night and needing to eat something (never have done this before )

• feeling super tire

Yes might be over thinking but it’s weird. Anyone else with crazy stuff going on so early in the tww?
