I am trying to figure out this movie?

its about a young black couple, female ends up getting pregnant and the boyfriend sticks around...she struggles to keep the relationship together cause they are not sure they can do this just yet, well the only part of the movie i remember is at the end they are both sleeping in her bed, and she awakes with blood everywhere on the sheets, her water broke or did something, she eventually has the baby in the bed, with the help of her boyfriend delivering it. after baby is born she doesnt want NOTHING to do with the baby tells him to "get rid of it" ....so hes walking down the street with baby wrapped up in a sheet...and he puts the baby near the dumpster. i cant really remember what happens after that, but i have been searching for this movie for the past year and i cannot seem to find it. can someone help?
