Not sure if it is due to JG or not.. but this is my experience..
Been trying to have kids for quite sometime but unsuccessful. My first child arrived after i had my first JG....I was so happy that i wanted to give the therapist a big ang bao cos she told me JG would help in fertility...haha. After our first child...we were unsuccessful again for 2nd kid..untill i had my 2nd JG (same therapist)!
I contacted her early this yr for my 3rd JG...sadly, she not working anymore. Nice lady from taiwan.
