Help! URGENT! i am doing a debate tomorrow morning on Roe v. Wade and i dont know any thing! help?

i am arguing affirmative(against roe ,defending the Texas state) please help give me a lot of material and also I need to be prepared to answer what the negative might say during the cross. I am doing the 1st affirmative- tips would be great because this is my first time debating. If you can use less complicated word that would be be good because i am only a freshman in High school. I need material latest 12:00 am(at night). Thanks in advance
