Missed period for multiple months.

[sweetxsimplicity]

I was going about my day as normal today, when a text comes from a friend complaining about her period. I console her and tell her to take some medicine, stuff like that. Well, then I realize that I have not had a period since late March to early April of this year. I had taken a pregnancy test in about May when I realized that I was indeed late and the results were negative. However, I'm now worried because I still haven't had a period to date. I realize that there's a possibility that the test was wrong, even though I'm not showing or anything... In fact, I've lost a lot of weight over these past few months. I've also had a lot of stress and lifestyle changes over these past few months as well, and I'm aware that those things could be the root of the problem... I want to go to the doctor, but I'm still 17 and don't wish for my mother to know that I was/am sexually active. So my questions are these: Is a GA gynecologist (or any other doctor I have to see for this kind of issue) legally obliged to tell a parent their child is sexually active? Should I be incredibly concerned that I haven't had a period for this long? And what could possibly be wrong with me, since I am most likely not pregnant?

any doctor that you decide to talk to or see about your problem in no way should inform your parent that you are sexually active if they do tell you can sue him /her for giving out your private information.

I don't think they have to tell. Your over 16 so really its up to you.
