1 hour glucose rant

Guys I failed 😞 and this time I’m very particularly upset because this time this pregnancy I changed everything my lifestyle and I started exercising! With my daughter I ate whatever I wanted and NEVER WORKED OUT so it was no surprised with already being overweight I failed my 1 hour and passed my 3 hour. My first pregnancy it was 5 years ago since than I’ve lost 60 pounds and maintain a clean bill of health. And I so I thought I’d pass my 1 hour with flying colors and I failed what did I do wrong now I have to go do a 3 hour! Did anyone pass the 3 hour but fail the 1 hour TWICE?!?
