How can I get pregnant after an arbotion?

Same as before . You do exactly the same thing you did before when you got pregnant before the abortion. Have intercourse around the time of ovulation. Ovulation occurs consistently about 14 days before your next cycle. If you know how many days there are from the first day of the bleeding to the next during your normal cycle just subtract 14 days. This allows you to predict when you should be ovulating.
