Well, if you aren’t pregnant, there are several things that can cause your period to disappear for a while…
Birth control can sometimes do that to you… If you are taking birth control pills or something that may be the cause.
Stress is also something that will take away your period for a while.
If you are undernourished, or if you work out for more than an hour each day, both of those could be the reason.
Also sometimes your body just takes a rest. 🙂
If you are really worried about it, or you feel like there is something wrong, you should go to the doctor.
Let us know how it all works out, ok? 🙂
