My due date was just bumped back 2 wks. Should I be concerned?

Your doctor knows your circumstances with your medication. If they are not worried, you probably shouldn't be either. And by moving your due date, that means they are not worried.

The same thing happened to me, I was pushed back 2 weeks. What can you do anyway if you 'should be worried'? You need to discuss your concers with your midwife and trust their decisions :)

2 weeks is not a lot of time. Some doctors count the 2 weeks before you conceived in your pregnancy and others don't so that could account for the difference. I don't think you should get a second opinion, but you should definately call the doctor who was taking your gall bladder out that the baby measured 18 weeks instead of 20. And, in the beginning the baby is so small, it's hard to tell the age, so as you get farther along in your pregnancy, its not uncommon for it to change. I mean, your due date is really an entire month long, and the EDD you get is just the average of the 1st and last day. My due date was Jan 9th, but I went to the hospital to get an ultrasound and the machine said December 28th. I wouldn't worry about a 2 week difference, because all babies develop differently, but definately tell your doctor only because of the gall bladder, but I think when he said small he meant like 4 weeks smaller or something, but just make sure. Good luck!

I wouldn't worry. The due date or dates that you are given during your pregnancy are just estimates. Also, remember that baby's go through rapid growth spurts, and can be measuring differently at different times. The ultrasound tech at my doctors office told me that if a woman had an ultrasound every week throughout her pregnancy, she would be given a different due date constantly. She also said that there is about a margin of error 2 weeks in either direction, meaning that the baby may measure 2 weeks ahead or behind, and most of the time the doctor will leave your due date the same.

As long as your doctor isn't worried about anything, I'd just relax. They may do another ultrasound later in your pregnancy to check the growth and development (Its called a bio-physical profile...I'm actually having one today...I've been suffering from high blood pressure for the past 4 weeks, and they want to make sure the baby is still growing and developing ok), and the baby may be right where he/she should be.

Everything will be just fine.

Good luck

They always use the first day of your last period as the beginning of yoru pregnancy until you have an ultrasound to be sure. When I first got pregnant, they told me I was 5 weeks, but I KNEW my conception date, and knew I was only 3 weeks. Your ultrasound is the most accurate way to know about when the baby is due. There's no need to get a second opinion. My due date went from November 29th (with my estimated period), to December 10th... a 2 week difference.

:-) Everything is fine, and its completely normal for your due date to change once you have an ultrasound.

Your not guaranteed to ovulate, when they say you should, so the original due date is just a guess. It's an estimated guess, but just that a guess. You could have ovulated 2 weeks later than what you thought. The ultrasound measures the baby, and growth developement, and would be the most accurate way right now to determine the actual pregnancy due date.

It could be possible your baby is smaller than expected, or your first due date was incorrect.

Remember, due dates are always GUESSES, 2% of women deliever on their due 'date'. Really it should be a due month!

Mine was changed several times. From the 1st, to the 13th, to the 10th, back to the 1st, then finally to the 15th.

My son was born on the 5th.

But in your position, a second opinion is a must. To make sure you baby is in perfect health, and make sure you're not suffering health wise either.

No offense, but my problem with midwives is that they often have a hard time turning over care to a Dr. when they should. You have a complex medical history to begin with & an OB Dr. does not usually change your due date that late in pregnancy. If you said that your period and 1st trimester US were off by two weeks, then I would believe that they would base your due date off of your US (common practice), b/c the 1st trimester US is the most accurate. I would seek the opinion of an Obstetrician

OB/GYN RN & mom

A due date is an estimated due date. It can easily go 2 weeks in either direction. However, you need to do what makes you comforable. You don't want to cause any stress to you or your baby so if a 2nd opinion is what you need to relax then get it!

I have been told by my doctor that after the first trimester your baby can measure two weeks big/small and still be due the date they told you originally. I don't think she should have bumped the due date. But that's just me.

Getting a second opinion isn't over reacting. Go see a real doctor. Midwives are great, but they don't have the medical training, and in this case I would feel more comfortable with a full fledged doctors opinion. You don't have to change doctors, just get a second opinion.
