Week 39

Your baby’s crown-to-rump length at this time is approximately 14.4 inches and the total length is approximately 21.5 inches. The average baby weighs a little more than 7 pounds now and is preparing for birth. You are probably as big as you are going to get and may be uncomfortable now. Most women gain between 25 and 35 pounds during their pregnancy. Your uterus is about 7-8 inches above your bellybutton now.

Although your baby continues to grow and develop inside of your uterus, there is not much room for him to move about. All of your baby’s organ systems are now complete and the lungs were the last to fully mature.

If you are uncomfortable with your pregnancy at this time, you are not alone. Most women are ready to deliver their babies. It would be very unusual for you to not be uncomfortable at this time. Your uterus has grown a lot and now fills your entire pelvis and abdomen. Try not to ask your doctor to induce you, unless it is medically necessary. Your cervix is ripening in preparation for delivery and your bladder is under a lot of pressure. You may feel nervous about the upcoming labor. You will know when you are in labor because contractions will get worse when you move around and they will also get stronger and more frequent. Other signs of labor are the breaking of your water or a bloody show as the mucus that plugged your cervix becomes dislodged.

Most of the lanugo on your baby should be gone by now. Your baby still may have some on his shoulders and in the creases of his body. Your baby’s toenails have reached the end of his toes. The umbilical cord is about a half inch thick and may be wrapped around him. The umbilical cord still supplies the baby with nutrients that he needs. After delivery, your baby’s umbilical cord will be clamped and cut. After it is cut, he will be an independent human being and must perform all of his body functions on his own. Your baby will get antibodies from your body that give his immune system a boost.

    Can't believe it is 39 weeks for you!!! Any contractions yet? It can't be long:)

    I know...it's so crazy! I can't wait!! No contractions yet. Really no signs of labor.

    So, my belly has drawn forward. Is that a sign that labor is close? I have an OB appointment today, so maybe I'll see how long they'll let me go before they want to induce. I don't want to be induced.

    Good luck at your appt! They may strip your membranes today to try to get things going. I was induced with my first and I'll never do that again unless there is a health risk to me or the baby. That was the most painful and long labor I've had. They thought I was 42 weeks but I had 35 day cycles back then so I think the dates were skewed since they base them on a 28 day cycle and the first day of your last cycle. This time I had an ultrasound to date the pregnancy very early which I think is more accurate. I know that the last weeks are miserable but I would say that it is worth the wait to not be induced if possible. My other two labors were a breeze in comparison to that induction. I don't mean to scare you but I wish someone would have warned me:) Let me know what they tell you today. So exciting!!!

    Don't worry...you aren't scaring me! I have heard that about inductions before and I already told them that I wanted to avoid induction unless it was medically necessary. Our 'plan' is to go without any kind of medication, so I really want to avoid anything that will make it harder to follow through on that. They didn't do anything special today. They just said that if I'm back next week, they'll check my cervix, which may be enough to tip me over the edge. They don't consider me late until I have gone a full week after my due date. My next appointment is Tuesday, so I'll be 40+2 then. I'm pretty sure that our 'true' due date falls anywhere between the 26th-29th, because we were trying to conceive and I was tracking everything at the time.

    Nice! It's good that you know when. I was nursing and did not start my cycle yet when I found out I was pregnant this time around so I had no idea when it happened. That's why I had the ultrasound. From what I read, sounds like the early ultrasound date is pretty accurate. I had an appt this morning too - same old thing; weight, blood pressure, measurement, heartbeat. All 5 minutes:) My next one is next Thursday at 38 + 2. Hope to see an update with progress from you soon:) I've been having mega contractions (6 within a half an hour last night) but they disappeared when I got up to take a shower. It drives me nuts because I always assume that its false labor but then start to wonder 'what if this is real?' Doc said this morning to call if I have more than 4 in an hour... I laughed because that happens every day.

    39 weeks tomorrow! I have an appointment in the morning and I'm trying to decide if I want my midwife to check me or not. I'm a little curious but I know it's still early. I'd just love to have a baby this week!!!

  8. kentsmommy 26 February 2015

    JDH - I wouldn't say that you are early:) Good luck at your appt! Hope to see some good news from you soon!
