UPDATE: 3 months late and NEGATIVE tests

im concerned bc my belly has hardened at the bottom and i cant suck it in at the bottom no matter how much i try

sometimes i have a little bit of nausea in the mornings

my dogs are all of a sudden super protective over me

ive been more emotional

HAS THIS EVER HAPPENED TO ANYONE AND THEY TURNED OUT PREGNANT?

UPDATE: I went to the ER because i was having pain in my right side. They did an ultrasound and i am NOT PREGNANT, but i have an ovarian cyst on my right ovary, however they still dont know why im not getting my periods
