Struggling with Infertility: Seeking Advice

Hey guys. So for the past 2 years or so I have tried to get pregnant. I feel like I've tried everything in the book.. Every where I look I see someone pregnant or having a baby. I feel so broken and hopeless.. like I'm barely a woman.. The thing is I've never really had regular periods. I will have one then not have one for a year or so. It's crazy. I've had hormone and blood tests. Ultrasounds and basic things like that. All have come back inconclusive. No one has any answers on the lack on periods or the fact that I can't conceive. I have yet to go to a specialist but I don't have health insurance. I have never actually conceived or lost a baby.. like I'm not even capable? Does anyone have something similar or have any advice? anything helps. Thanks ❤️
