You may have had a longer cycle and become pregnant a little later than you thought. There is only a week between these 2 dates so it is not enough to worry about. with my first pregnancy, my dates said I was due on September 23rd and my scan said October 4th. I knew I had intercourse on January second, so I guess it just took a while to implant. I didn't get a positive pregnancy test until February 3rd, which would be about right. Second time round my dates and scan were the same and I had a positive test on the day after my missed period. The only time it really matters is if you had sex with 2 men a week apart and need a best guess as to which is the father.

Q: Is it more accurate if your doctor gave you a due date of February 18 and said you were 21 weeks pregnant but an ultrasound showed you were 20 weeks and had a due date of February 25?

How long after a woman is pregnant can she find out what gender baby she is having?

Are you pregnant if you took 3 pregnancy tests and got different results and an ultrasound showed that you were not pregnant but your stomach is getting bigger?

If you have a test that shows a positive pregnancy result then YES you ARE pregnant. Forget the negatives. A positive is a positive. A ultrasound can not detect a baby till you are 6 plus weeks into your pregnancy. Actually you can see an embryo earlier than 6 weeks. You should go back to the doctor and get another ultrasound. This could be a molar pregnancy. See a doctor, they will be able to give you a blood test and tell for sure.
