Okay I'm looking for a WIP fic I read. It was a good while ago so I don't know if this fic has been completed, is still a WI, or has been abandoned. What I remember is that Harry is attacked by Blaise and Blaise impregnates Harry using a fertility potion. After Blaise attacks Harry he leaves him locked in a room battered and bruised. Draco helps Ron and Hermione find and rescue Harry. When Harry finds out that he is pregnant Draco convinces Harry to keep the baby. Over the course of his pregnancy Harry and Draco fall in love and eventually get bonded. The baby is born but at the babies birth announcement Blasie drops the bomb that he is not the father but Voldemort is. That's where the story left off the last time I read it so that's all the details I can give you.
