Harry and draco went back to school for them to finish thier last year but it was only them two.
They became room-mates and after 2 weeks of fighting they became friends. But that's what everyone else thinks but really they were dating and had been since 6th year.
One day harry woke up vomiting he didn't understand because after a bit he felt fine. So he went to madam promfrey where he found out he was pregnant but would give birth after school year.
After some time the couple told the school and dracos family which were surprisingly supportive.
After that they lived happily with 10 kids, both with jobs as teachers and all kids lining up to go to hogwarts to either start or enjoy another year.
