Gf called me one time at army bct..when she first got there...?

My gf called me one time when she arrived for bct. Sayin her training won't start till the next day. We talked 3 minutes. Then her phone cut off...she called me back but i was showering. I was going to ask her for the address so we can write..is it possible that she'll call me again..or write to me in the next 2 weeks?? I dont want her to think I was avoiding her call.
