My baby boy was weighing in at 3 pounds 2oz at 30 weeks. That was .07 ounces more than what glow estimates. So 5 weeks later should I keep adding .07 to what glow says for a good estimate? I don't get anymore measurements until next weekend. I just do not plan on delivering an 8 pound baby. I know measurements can be off. Nothing is never exact. But at this rate he will be 8.5 pounds at 40 weeks. I'll definitely induce by 7.5 pounds
