My wife age is 28 & had miscarriage during 27 Jan'16 (4th month). During 3rd month pregnancy scan she had OGT & her
sugar levels are normal. But after miscarriage OGT test was taken during March'16 as per doctor advice and test indicated she is having sugar. Please advice what could be the possible reason for sudden increase in sugar level? If this would cause any threat for conceiving for second time?
