I (20F) have had irregular periods somewhat throughout my life. This year has been the worst with it. I only had 2 periods so far this year and I had one in February and then one in June. I am going to the gynecologist about it and I'm just so stressed about it. This past semester I was super stressed about school because I was taking 2 really hard classes that I thought I'd fail. During March-May of that semester I had no periods and finally in June I had one. Then, in July, I missed again and I still have had nothing to date in September. I have no idea what is causing this. Ovarian cancer? A brain tumor? PCOS? What are your thoughts? It may be due to stress but I'm really not sure :( Just seeing if anyone has had the same experience.
