Finally I'm pregnant BUT.....

Kelly
After going through <a href="https://glowing.com/glow-fertility-program">IVF</a> treatment, I'm finally pregnant! We are so happy and excited but I am also really nervous till next week appointment to hear the heartbeat. :( 
I'm currently on 5w4d. And I have no pregnancy symptoms. I feel sleepy and breast pain sometimes but I think it's just because I'm on progesteron meds.  
I'm confused. Is it ok not to feel morning sickness at this point? 
Has anyone transferred  PGSed embryo and ended up miscarriage? 
I wish I could just enjoy this happy moment.:(
