Okay, I think I posted here last month saying that I missed my period. And I'm really worried about missing it this month too. I'm 17 years old but there's no way I'm pregnant. I'm a virgin and I've never had a boyfriend or anything. What I'm worried about is...well, firstly I exercise and not exactly excessively but I really push myself. Probably more than I should and it puts a lot of strain on my abdomen so I think that might have stopped my period. I used to exercise excessively but I don't anymore. But I don't know if that could've done it? I am considered to have an eating disorder because I don't eat enough or if I do, it's not the right foods. I only ate one proper meal today because my mom makes me eat and I do if she's watching. I am a healthy weight for my height but my eating and exercising habits are abnormal. To be fair, I did get a bit of spotting last time so I thought I'd get it eventually but I never did. I think I waited a little over a week and I usually get it in 2-3 days. So, it's the 23rd and I'm usually due around this time...maybe more around the 27th or 28th but usually, I'd start getting cramps or bloating before I get my real period and I haven't gotten any symptoms yet. And honestly, I wouldn't be worried about never getting a period again because I hate them but my friends said I could end up getting cancers if my body doesn't clean or flush itself out. I don't know if missing two consecutively is a problem. And I haven't told my mom that I missed the first one so I'm scared. I have three questions: Should I be worried that I haven't gotten, well, the first period to begin with and possibly a second one too? And should I wait until the 27th, 28th, 29th to see if I get it? And what do I do if I keep missing them?
