Will I ever get to be a mom???

Month 3 of a negative pregnancy test! I wouldn't be so frustrated if I wasn't paranoid about being infertile. Last year I was hospitalized for 3 days due to pelvic inflammatory disease, and since then I have been worried sick about being able to get pregnant. The doctor's don't want to do any fertility testing as of yet because they tend to hold off with young people(I'm 24). I know that many people on here TTC for years before becoming pregnant, and I give you all a ton of credit for being patient as you can be. I'm just so frustrated and scared that I can't give my husband a child. I am so ready for raising kids to the point I tear up every single time I see a baby. How the heck do I keep my cool? I know Stress doesn't help my case at all. Just the sight of a baby or baby department of a store makes me break down in tears. I don't know what to do, it's not like I can talk to anybody about the issue, as it is very personal.
