Do i have to take medication if i failed 1hr glucose test?

for me, I had to record my food and blood glucose level before and after every meal and try to avoid or eat lesser portion for those food that affects the glucose readings. no medication or insulin during this period. it got worse as baby grows in tummy so I had to self inject insulin before every meal towards the end of pregnancy. aft giving birth I continued to "control" my food and passed the glucose test which was scheduled 6 wks aft giving birth
