Periods during military training? Help?!

Kaylee

The last time I had my period was the first week of basic training. I figured it was normal to not have a period through basic training due to the increase of physical activity, but I graduated basic training and have been at job training for the past 8 weeks now, and still no period. I have the nexplanon implant, which sometimes causes me to have less frequent periods, but never this long. Is this anywhere close to normal?
