Yes, a pelvic ultrasound may not be able to detect a pregnancy for weeks after conception. Urine pregnancy tests are the typical first step in diagnosing pregnancy.
How soon
If my memory serves me right at least an hour before, and they want you to have a full bladder which hurts because you have to sit there and wait for the ultrasound.
The doctor can see the baby as soon as the baby is about 3 months.... the baby is not fully developed but you can see the baby real little the doctor will show you the head arms, ect. but it wont be as clear......
Was that a pun? To soon to tail? Just got back from my 16 week ultrasound. Doc says she is positive the baby is a girl because she saw an equal sign.
Any moment now.
About 3 months, usually respiratory system of the baby develops at 12 weeks of age. ** The fetus's heart starts beating at five weeks gestation. Through an ultrasound you can see the ultrasound at about 6-7 weeks. With a fetal Doppler you can hear the heart beat at about 9 weeks.
At the first ultrasound
It can happen pretty quick. Sometimes as early as 5 weeks. When the baby becomes larger, the uterus will rise above the pelvic bone and you will begin to show, AND take the pressure off your bladder. However as the baby grows bigger still and maxes out the space in the uterus and drops the pressure will return along with the frequent bathroom breaks.
at 6 weeks you can see the heart (it will be a very tiny circle that is beating) and see a small oval shaped fetus in the uterus. you cannot tell this soon about the sex of the baby or any other features like hands or feet. the sex and baby's features can be determined at about 21 weeks on ultrasound.
An annual Pap test and pelvic examination beginning as soon as young woman becomes sexually active, or between the age 17-20 years, are the most important diagnostic steps for early detection of uterine cancer.
On the first ultrasound at about 3 months
In March I was 10 weeks pregnant and was spotting very lightly. I went to the hospital and they did an ultrasound. They told me that at 10 weeks they should be able to at least see the heart beating even though it might be too soon to see the baby. When they did the ultrasound all they saw was the sac. There was no heartbeat. I had a full miscarriage a few days later. It was determined by blood tests that I had miscarried about five weeks prior and was just now discharging the fetus. I pray that this is not the situation for you, and you have a healthy baby!
