40 Weeks Pregnant – Time To Give Birth (Maybe)

40 Weeks Pregnant MomBeing 40 weeks pregnant, you may be impatient or worried or probably both. It is definitely time to start learning about giving birth and preparing your birth plan if you haven’t already.

Your baby is ready to be born, but that doesn’t mean labor will start when you want it to. Many moms will have to wait another week or two. Tired of waiting? Learn about inducing labor naturally here.

Your Baby’s Development

Fetus at 40 Weeks Pregnant A big week for mom and maybe for baby. It’s not unlikely though, that your baby will sail through this week completely ignoring the fact that this is supposed to be the last week of pregnancy! But if labor starts, your baby is definitely ready to be born!

Depending on your own genetics and body composition, your baby can range in size as a full term infant from 7 pounds (3 kg) and above. Some babies are born smaller while others can tip the scales at 9 or even 10 pounds (4-4.5 kg). Estimating an unborn baby’s size can be tricky. While doctors can use methods such as ultrasound measurements and estimation, the baby’s true weight will not be know until they actually arrive.

40 weeks pregnant, there is practically no room left in your uterus for your baby, and you may feel more pressure as your baby stretches and continues to move within. Some will say that your baby’s movements will slow down during this time due to lack of space, but you should still be able to feel regular movements each day.

Your medical practitioner may have you keep a record of counted movements to ensure regular activity during this time in your pregnancy.

Baby just bornThe exact time that your baby arrives is of course not always as expected (unless your’re having a planned c-section, of course). Many babies will either show up before or even after the predicted due date, with very few actually being born exactly on time.

Do not get anxious if you have reached the magical 40-Week mark and are still waiting for your new baby. Remember that when your baby is ready, she or he will enter the world and not a moment before!

Actually, the way we calculate due date, may not be completely correct, as research has shown it to vary. Already in 1990 (reference below), researchers re-examined the length of pregnancy for American women. Results indicated that for first-time Caucasian moms, an average pregnancy lasts 274 days from conception (i.e. approximately 288 days from the first day of your last period). That is 41 weeks, not 40 weeks!

Second time Caucasian moms gave birth approximately 269 days after conception, which is a few days after the end of week 40. Non-Caucasian moms had slightly shorter pregnancies, for example the average pregnancy for African-American women was 266 days, counted from conception.

Either way, you can be certain that you will NOT pregnanct any longer a few weeks from now!

Mom’s Body

40 Weeks PregnantHeavy and uncomfortable. And impatient and nervous. 40 weeks pregnant, you may feel a variety of emotions that continue to build as you prepare for giving birth.

Many women find themselves extremely uncomfortable now and unable to do many daily tasks easily such as tying their shoes, carrying groceries or even climbing a small amount of stairs.
Remember that the end is near!

Some women will be impatient and want to try to get labor started through natural methods. Although there may be some things you can try, nothing is guaranteed, but it may be fun to see if one activity will work over another if you have been waiting for some time. Nipple stimulation, walking, intercourse and even acupuncture or homeopathic methods are just a few options that women have tried in the past, some with positive results. If you want to learn more about naturally induced labor, here are tips on several ways to get labor started.

Do not try any self induction methods on your own without first asking your doctor or midwife if it is OK. While some options may seem harmless enough, you should always check with your doctor before consuming cod liver oil or any herbal remedies in order to start your body for the birthing process.

While waiting, you can spend some time preparing by reading about giving birth or taking care of your baby, for example.
