Due Dates
Conception Dates

If an ultrasound at 14 weeks showed your due date as Oct 2 and an ultrasound at 20 weeks showed the same but a 28-week scan gave a Sept 23 due date could you have conceived before Dec 12?

Absolutely not. The later in pregnancy the less accurate the scan. The first two giving a due date of October 2nd will be correct and give you a conception date of around January 9th.

I was 6 weeks pregnant and it showed on the ultrasound the little heart beat. its was so cute!

It depends if you were five weeks pregnant or five weeks from conception. If five weeks pregnant you conceived around 18 May, if five weeks from conception you conceived around 4 May. If you could see a heartbeat you were 5 weeks from conception.

The scrotum is the sac around the testis and the ultrasound test that was done showed nothing abnormal. Everything is fine.

Ultrasound gives an estimate of the age of the foetus. At this stage of the pregnancy, it's quite accurate, but it's still only an estimate, and the date of conception could be a few days, even a week, away from the date 19 weeks and 2 days ago.

My result of my ultrasound showed no soft makers. is this a good sign that my baby will not have trisomy 18.

You have two due dates...one accourding to your last period and one accourding to the size of the child on the ultrasound...i think the ultrasound one is more accurate

NO! My pregnancy hormones decreased and they thought it was a chemical pregnancy but my baby showed up on the ultrasound 2 weeks later. NO! My pregnancy hormones decreased and they thought it was a chemical pregnancy but my baby showed up on the ultrasound 2 weeks later.

We saw our baby for the first time on the ultrasound today.Human ultrasound in the oceans is now considered a major noise pollution as it confuses marine creatures like whales.

Hi, It is possible to be pregnant and have a negative urine pregnancy test. It is also possible you could be pregnant with a negative blood test providing that the blood test was performed too early. This could also be why the ultrasound showed signs of pregnancy. Also if you miscarried recently without you knowing, it is possible the ultrasound picked up the sac minur the embryo. If a embryo is picked up on the ultrasound then you're pregnant hun.

The ultrasound is as conclusive as it gets. The tests have a small margin of error because they test for hormones. The ultrasound sees what is there or not. You are most certainly pregnant. Possibly with twins. If you are still early on the ultrasound can be inconclusive about that. Sometimes one of the twins will be reabsorbed into your body early on as well. I know one person that showed twins early on but only one in a later ultrasound. I hope that this is good news for you and that both babies are born healthy.

yes! i went in for an ultrasound and thought i was 7 weeks and having a miscarriage. The ultrasound showed no embryo only a yoke sac. I went to my regular doctor the next week and it was there and i was 7 weeks on that day. so just wait it out!

This makes no sense and this question should have been asked to the ultrasound tech when you were there.

It's supposed to have to veins. 2 Veins and 1 Artery in the umbilical cord. Think AVA.

The term loves means means commitment to a course to be there for someone, to care, to be kind. Love is conceived in the heart and showed outwardly.

this could be normal. it can take up to 6 or 8 weeks for a fetal heartbeat to show up with a vaginal ultrasound.

An ultrasound at 6 weeks should show a fetal heartbeat, if there was a fetal heartbeat you're not miscarrying.. It's probable you estimated your due date wrong.

As the ultrasound scan showed everything was normal I wouldn't worry too much. However, I would ask a medically qualified person to clear your mind before you start using the oil again.

Well as no one else has answered my question I will update this situation. The 3 week follow-up ultrasound which the Technician said showed nothing actually shows an poorly defined area of hypoechoicity of now 1.9 x 1.0 cm...upcoming biopsy.

An ultrasound doesn't have the resolution to show eggs in your tubes. Are you sure the report didn't say that you had follicles? Check the report and talk with your health care provider to clarify the situation. You can ovulate on birth control, but I have yet to see an ultrasound report that documented "eggs in the tubes."

Assuming she is qualified and experienced at her job she is probably right. However the ultrasound is not 100% accurate.

Yes, though conception can occur at irregular times during a cycle. Typically, two weeks into your cycle you are able to conceive. Your due date is calculated based on the date your last period ended (because it is impossible to determine precise conception dates), therefore a woman at 7 weeks 5 days conceived approximately 5 weeks 5 days ago. Fetal measurements can also be off for your specific child, though.

Minor spotting doesn't always mean you have miscarried. Your best to check things out with your doctor, but if your baby showed a normal heart-rate just 2 hours previously, the chances are everything will be fine. But get checked out just in case.

I just had this happen. I am 4-5 weeks and had a vaginal ultrasound and nothing showed. The ultrasound specialist, radiologist, er dr and an obgyn all told me that's normal around this time. I went back for bloodwork the next day and my HCG levels doubled. Good Luck. =) They have my "official" ultrasound scheduled at about 10 weeks.

I went for my ultrasound today. I am 7 weeks 4 days. I was told a normal fetal heart beat would be 120-180. My ultrasound showed a heart rate of 142. My friend told me that hers was 140. Hope I helped. Keep praying. Shaun
