OGTT at 32w

I had previously gone for my 24w OGTT test at KKH and passed. Now due to relocation to another country, the clinic repeated an 1hr glucose test on me and I failed. They wanna do another 3hr glucose test on me at 34w. Any moms have the same experience where you passed the glucose test and failed later on? #advicepls #pleasehelp #firstbaby #1stimemom
