too young to be a mom

Victoria
I want to get pregnant but everyone around me tells me not to because I'm only 20 A few people got my hopes up thinking I might be (including my grandma) so she made me go to the doctors to get a test taken. It was negative so I'm kind of upset about it. My moms ok with the thought of me having one soon but my grandma constantly comments on it about how I don't need one and that I need to get on birth control. I can't go one day without hearing a snarky little comment about it from her and it's really starting to irritate me and my boyfriend too.
