5 week 6 day ultrasound and no yolk sac seen inside gestational sac, is this normal? I recently had a miscarriage and immediately got pregnant again so conception date isn't known. Ultrasound last week measured me at 4 weeks, 6 days. 7 days later, it had grown to 13 mm or 5 weeks 6 days size. Doctor couldn't see a yolk sac, but I have a tilted uterus so is it possible the pregnancy is viable & sac just not seen yet? My HCG, progesterone & estrogen are all in excellent range.

The short answer is that, yes, knowing your date of conception may be able to make your due date slightly more accurate. However, a due date is still difficult to pin down. This is because it can take a variable amount of time for an egg to become fertilized, and for that fertilized egg to implant and begin to grow, before pregnancy actually occurs. Generally speaking, your due date will be determined using what is called ?Nagele?s Rule.? This method for determining due date was developed by Dr. Nagele in the mid-nineteenth century. Dr. Nagele calculated that the average pregnancy lasted 266 days from the date of conception, or 280 days from the last menstrual period (referred to as LMP). This is where we get the figure that pregnancy lasts for 40 weeks ? 40 weeks is exactly 280 days. The thing is, even using the LMP date isn?t exactly accurate. 280 days is just an average. This can be different based on any number of factors. For example, ethnicity can influence the time it takes for your baby to be due. It can take 288 days, for example, for a first-time Caucasian mother to have her baby. The mother?s age, her nutrition, and even her weight can push the due date one way or another. One way that some women can get a more accurate due date is by measuring Basal Body Temperature (BBT) and Luteinizing Hormone (LH). Measuring these two factors can tell you exactly when you ovulate. By adding 266 days to the time that you ovulate, you can come up with an even more accurate due date. There may be other ways to help figure out a more accurate due date, as well. For example, an experienced health care provider may be able to help determine your due date by using ultrasound technology to determine the gestational age of your baby, and thereby calculate your due date. Another way to calculate your due date is to track HCG levels in early pregnancy. For a normal pregnancy, HCG levels double roughly every 2 1/2 days. Your health care provider may be able to perform these tests to help determine your due date.

I am right now in the process of my 2nd miscarriage. It is a horrible thing, physically and emotionally. I would not wish this pain on anyone. One in every 5 pregnancies ends in miscarriage, and one in every 4 if you are over 35. A true miscarriage occurs during the first 12 weeks of pregnancy. After that, it is still possible to lose the baby at any time (though the chances are much slimmer). A loss after the first trimester is considered pre-term labor. There are many things women should avoid during pregnancy to protect their little ones. Changing cat litter, soft cheeses, deli meats, certain wrinkle creams- all of these things can be dangerous to the unborn child. For a more detailed list with explanations of their dangers, see ---. This is a list of things you should do and should not do during pregancy and a great source of information. If a miscarriage is happening, there is unfortunately nothing you can do to stop it. The most common cause of early miscarriages is a chromosomal defect that keeps the baby from developing properly. Even if you do everything right and avoid all the things you should avoid, you cannot keep miscarriage from happening if there was a chromosomal defect at conception. Signs of a miscarriage are cramps, lower back pain, pain in the right shoulder (I had this with both of my miscarriages), bleeding, or a brown discharge. That was the first sign for both of mine. Some people will be able to miscarry naturally with no need for d&c, the procedure used to remove all fetal tissue from the uterus. An ultrasound should be performed to be sure all fetal tissue has dissolved or been expelled. If so, you don't need a d&c. If not, the procedure may have to be performed, or the doctor can give you medication to help you expel the rest. Keep in mind that a d&c scrapes out the ining of your uterus, which can make it harder to conceive the next time because the baby may have difficulty implanting. Also, many woman (like myself) have a tilted uterus, which makes it difficult to see the baby in ultrasound, so I recommend waiting a few weeks for another ultrasound before making a decision to have a d&c. See all the miracle stories on ---. No matter which option you choose, your doctor will need to check your HcG levels (the hormone produced during pregnancy) to be sure they get back down to 0. After that, you should wait at least one normal period before trying again. I got pregant the second time 2 weeks after my first miscarriage (I did not wait for the period) and it ended in miscarriage, also, so I highly recommend waiting for that normal period befor trying again. I sincerely hope you never have to worry about any of this, but that should answer your questions. Good luck!
