HI I am 24 years old and I think im pregnant,some days i'm showing some days im not.I tested twice and they both came negative but when my belly grows I get weird feelings like something is inside or like I am bloated.i've tried letting this go but everytime the tummy shows and i feel and look pregnant i panic and wonder if i could be.I still go on my periods for about 2 days a month.If I am pregnant it would be my 5th month so I should be showing.PLEASE HELP ME.
