So frustrated. Why can't I just be normal :(

OK I have pcos, my fiance and I have been trying for a year with no luck no nothing. Today I had a obgyn appt. And my doctor wants to run all these test to see what my body is doing. She also wants my fiance to take a sperm analysis to see the mobility of his sperm. And depending on the results we will see where we go from here. I'm so upset because I feel like everyone else can get pregnant but yet I cant. I'm just venting and this is the only place where I know others will understand.
