Choosing between a wedding & a baby 😣

Okay so I'm going to try to not make this long.......
Alil background story. Recently engaged to my man of 4.5 years. We are both 26 y/o. We've been having unprotected sex for 4 years, not really trying tho until the beginning of this year. Initially we were going to just plan our wedding for 2017-2018 but since we haven't gotten pregnant at this point I don't want to spend 1000s on a wedding then find out it may take 1000s to have a baby. My anxiety won't let me just blissfully do that. Plus I'll just be older so it may get harder. I just need to vent bc I have no one except Bae to talk to. Everyone is like "why aren't you planning your wedding?" "Why you don't have kids" &&& more recently since my little sister announced her pregnancy "I always thought you would have a baby first" 
After Bae SA(we should get the results in the next couple of weeks) I pray we can start to plan our wedding. All my blood work and hsg came back normal. My lh is 3x my fsh but my ob doesn't want to diagnose me with PCOS although once we get the SA back she will prescribe me Clomid. 
Just needed to vent. Thank you and baby dust to you all 😘😘😘
