I have two questions for you today.

I haven’t gotten my period in four to five months. I’ve gone to my doctor and he’s told me everything it could be, like weight loss or stress but I’m not stressed nor have I lost weight. In fact If gained a little. I know I’m not pregnant because I have taken a few pregnancy tests, even the blood ones your doctor makes you take. All came back negative. I have an ultrasound in a week, but I’m still worried. He said it may be an ovarian cyst but from my understanding they hurt, and I haven’t been having too bad of cramps. So, do you have any idea what it might be?

My other question is:

I’ve had an abnormal itch down there lately. It’s not my vagina hole either, it’s more towards my clitoris. And when I scratch, it just hurts and becomes itchy soon later, or the itch doesn’t even go away. When I feel my clit sometimes it feels like it might be a little swollen. Also it usually doesn’t get itchy until later at night. There is no discharge or anything like it is a yeast infection either. Do you have any idea what it might possibly be?
I also have no foul odor.
I have also had sex with only one person and both of us have been tested and are clean.

I am a 16 year old girl who has had some ovary problems in the past. I get cysts this time of year. The last cyst was said to be massive. About a week ago I started to have abdominal pains, so I went to urgent care. They said I had vaginiosis and a yeast infection. On valentine’s day I got my period but it was extremely light and only lasted two days which is unusual for me. I am going through some med changes for my schiziod affective disorder but that happened last month. Last month I started to have back pains… but I had a back injury when I was a cheerleader. Also from my meds and hospitalisations I have gained about 70 pounds.I read that weight gain as a teen can cause Ovarian Cancer before meneopuase. I have other symptoms too such as nausea, loss of appitite, abdominal pains (as I wrote earlier as well as back pains), dizziness, bloating and frequently going to the bathroom. I’ve also been crying from the pains and I don’t get cramps with my peroid. Can anyone help me figure out what is wrong with me?
