day before period.

Natasha

took a test this morning negative- app says to take it in 3 days but i'm impatient.

yesterday i had pinch like feelings in my uterus and now i'm having alot of pressure in my uterus area it's uncomfortable and making me nauseous, my nipples are always sore and my breast has been aching.

did i test too early or am i out? (cycle is based on 54 days, last period was july 20 i think)
