Just so you know, I am just shy of 36 weeks. My daughter has tachycardia (elevated heart rate) and Premature Atrial Contractions. When she comes out they’ll do an EKG to rule out any other heart abnormalities and treat those if they haven’t cleared up. Also, I am borderline with Gestational Diabetes (failed the first test and passed the second) and I have been dilated to a three for several weeks, now I am almost a four. Four centimeters is considered active labor right? Also, she is doing very well, she is “ripe” and at a healthy birth weight already. My doctor said something about maybe giving me an early induction. Not soon, I would be 37 or 38 weeks when they did it, but he said that certain circumstances make baby coming out a little early a better way to go. Would those circumstances be any of those? Is there a reason to induce early? I want her out of me and my mom will be visiting then and I want her here for the birth, I was just wondering why he might have brought it up.
