How early can pregnancy symptons come even without a missed period?

i knew i was pregnant 3 days before i missed my period, the first time heartburn was a major symptom. the second time i knew 1 week before my missed period and it was serious nausea and sore breasts. so pregnancy symptoms can appear early, but it all depends on your body. i know my body really well so i can always tell when im pregnant.

good luck!!
