Missed period

W

Im offically 3 days late tomorrow and ive been extremey tired and nauseous all week. I threw up earlier and have had such a sick feeling in my stomach. I tested yesterday (first day missed period) and the day before and got a BFN. Ive been feeling twinges and “shocks”down there but nothing near cramps. Maybe a backache once in a while. Been extremely bloated all week and i wish i had answers.

I have absolutely no signs my period is coming which is unusual since i either spot or cramp before.
