I had *and still do have* the opposite *period* symptoms. Unlike your's being over frequent, mine is kinda, under-frequent. The length etc. is pretty much normal (4-7 days) but I pretty much never know when its going to start. Sometimes it comes after1 month, sometimes 1 1/2 month, sometimes 2 months, sometimes even 3, and once or twice it has gone longer, but recently its been coming mostly after 1 1/2 - 2 months. My mom wants to take me to the doc but I'm terrified of the doctor (don't ask me why) and always refuse to go. Maybe after you go I can think about it. I did get a blood-test for my thyroid gland several months ago though (not a checkup, just blood test) and it came normal, thank God. I was worried about having a slow thyroid, but thankfully its normal. Its best to get checked though! *tell me that*

Anyway, I don't think it could be anything but a hormone imbalance now.........which I'm still scared to go to the doctor for, but someday, just someday, I know my mom will make me. Good luck and let us know how it goes!
