Infertility and marriage health

So I recently got married and we both want to start trying for kids in the next couple years. I just made an appointment with my OB just to make sure I’m healthy in that area. I do have some concerns, my mom had fibroids and although it took her a long time to conceive, me and my siblings are here. I want to get my hormone levels and everything checked while I’m at my appointment, because I have noticed since I was about 20 (I’m 27 now) I’ve had some dark chin hairs, and I know that’s a symptom of PCOS. My periods have always been irregular, but in the past two years since I’ve been eating more, they have only been off by 3 or 4 days at the most. I know I need to wait for my appointment to know for sure what’s going on or atleast the direction to go in for fertility options if needed. I’m having a big insecurity with this in regards to my husband. I’m having some extreme anxiety knowing that he would also be so sad if we couldn’t ever get pregnant. He wants to be a dad really bad. One day I brought up the option of adoption or foster care, and he said we will never have to worry about it so why think of it? I’m worried if we can’t have kids of our own, he will hate this marriage and regret it or think badly of me. I know I might not even have any fertility issues but I definitely think I have some predispositions to it at the very least. I’m just wandering if anyone else has struggled with infertility? How did you get through these emotions of not being good enough or having a failed marriage because of it? How did you make things better with your husband or SO?
