how do I tell my SO I'm pregnant? (long distance relationship)

I can't fly out to see him because of my exams until next month and he was just here a few weeks ago (obviously because I got pregnant)
He's working A LOT because he has medical bills to pay and the baby is unplanned but abortion or adoption arent an option.
Should I facetime him or call him? I'm going to university here in Germany and he's from California I don't know how we're supposed to do this?!
