Hi Jen,
Welcome to the thread! I can't answer all your questions, but I recomend you get the book "taking Charge of Your Fertility" You can get in online for less than 10-15$. It's a wonderful resource and explains a LOT about your cycle and how your body works. If I were you, I'd start charting and bbt asap. By bbt you can see if you're ovulating. When you go see a doctor, you'll need to have charts so the doc can see what you've been doing.
Also, don't worry about minimizing someone's situation. personally, 8 months is long enough to have some concerns, especially if you don't think your body is working right. We all have the same goal in mind, to make a baby!

It doesn't matter if we've been trying for a month or 2 years. Good luck! Keep us posted!
