Need help don't know where to go

I'm 25 years old and it has been 95+ days without a period, I've taken pregnancy tests that all say negative. I'm beginning to develop depression because I can't shake the feeling that I might be baron. Something is deafeningly wrong, when I went to a dr before she just shrugged it off saying periods can be inconsistent but My boyfriend and I have been trying to have a baby for over a year now. Everything is dry and hurts. I really want to see a real professional and get some answers or help. Where should I get a dr.'s appointment for this problem. Or to at least get a fertility test. Please please I need help with this.
