I'm only 19 and my boyfriend and i have been together off and on for five years now. Recently we got back together and we don't use protection when we have sex. My period is five days late and I've been feeling nauseous the past two weeks I'm always tired my stomachs is bloated and sometimes I get cramps. Twice I've had spotting but still no period, I've taken five pregnancy tests and they all say negative but I feel like I may be pregnant and I'm not sure what to do. I've never wanted kids and my boyfriend does I'm worried I wont be able to have kids and he wont want to be with me anymore.
