I honestly don't know why some of you worry so much about you're periods. Everyone complains when they have them, then they complain when they don't.
There is no evidence that infertility arises from not have a period for some time.
If you're eating properly and lifting heavy, then bone density isn't an issue either, especially if you're taking test.
I've know a couple of women BBs who haven't had their period for years. Bone density is above normal.
The most important variable in maintaining your period is adequate food intake. You can be 25% body fat, have an eating disorder and not have a period.
Last, remember, no period does NOT equal no ovulation. If you are really concerned, then stay on the pill.
