Freaking out

My SO and I have been TTC for the last 6 months. I am 34 and my dr decided he wants to do a procedure Tuesday to see if perhaps there’s something wrong or blocked etc. I’m so terrified that I’ll get bad news and it will change everything. I just want one more and I see these “women” all over getting pregnant on accident when they don’t deserve a baby and we are trying to add to our family and we are having a hard time. I’m so worried about bad news I could cry ...... Ugh
