How do I know if I’m pregnant ?

Amya

I think I’m pregnant because my stomach feels like it’s full all the time. When I wake up in the morning my stomach hurts and I feel nauseous.I can’t go to sleep in no position but on my side. My stomach looks bloated. I took a pregnancy test and it’s negative i don’t know what to do.But I know people that have got a negative test and was pregnant
