Going to the dr...

I'm really hoping for some feedback and support here. I have a Dr's appointment on Wednesday (April 20th) to discuss concerns. Hubby and I have been TTC for about a year now with no luck. I haven't had a positive opk in the past 2 cycles I've tried them. My periods have always been irregular and the past 6 cycles have been between 50-60 days all on different days. I've gained a decent amount of weight and also noticed I was growing hair in places I haven't before in the past 2 years. I really believe I have pcos. I have bad anxiety and don't even know how to bring it up to the dr. I really want to push for a diagnosis and treatment because I want a child. The last drs appointment I went to with concerns when I bled for 3 weeks almost 4 all they wanted to do was give me BC. no tests or anything. I'm so so nervous and just want to be normal and have a child...
