there is no law. i was pregnant my senior year in high school went homebound when i was about 37 weeks and i stayed homebound for 6 weeks and went back to school. when i was homebound they had a special teacher that would go to my house and take me all my work and would take it back to my teachers every week. they asked me if i wanted to go to the alternative school and that it would only be half a day so that i could spend more time with the baby but school was almsot over and my husband would take care of him so i finished out the year luckily i grad the same year. don't let them tell you that you have to go to alternative because you don't.
