Please help, advice needed on pregnancy dates confusion?!? ?

i would be extremely appreciative if anyone could offer me some advice!


I was given an EDD at an 9week and 6 day scan of 25th jan. Counting the 25th jan as my 40th week of pregnancy, means that i got my first positive pregnancy test on 4th may at exactly 2 weeks of pregnancy. this doesn't make sense to me! My last menstrual period prior to this was 3rd april which would have given me an edd of 7th Jan and would mean that the first positive preg test would have been at 5w 3d pregnant.


many many thanksPlease help, advice needed on pregnancy dates confusion?!? ?
With Ultrasounds, anything before 12 weeks is based on measurements of the baby. Anything after 12 weeks they say can be out by up to 2 weeks.





So, your period was 3rd April. You wouldn't have ovulated until about the 10-15 April on a standard cycle. You could have ovulated later.


(Though the 4th May does sound a bit extreme)





Your positive pregnancy test could have been at 2 weeks, as your body starts producing hCG hormone when your baby implants into the uterus. This could have been early for you.





Your baby could also have been slow at developing. It's not unusual or bad, but it does mean you have a chance of having a small baby.








My first ultrasound showed i was 6 weeks 4 days. They told me to come back for my 12 week ultrasound in 4 weeks. I booked the appointment that day for 4 weeks later, but when i went in the baby was only measuring 10 weeks, and i had to go back 2 weeks later.


I guess it depends on the person doing the ultrasound as well, and how far out they stick the measurements. When you watch, they don't have a lot of room for mistakes.Please help, advice needed on pregnancy dates confusion?!? ?
You ovulate around 2 weeks before your period or after (either way between day 10-14 of your cycle). So this makes sense. Some family planning centres/drs take it back to the date of your last period which is the date your thinking of, however if they've done a scan and such then i'm sure they know what they're on about. However wait til the next scan and when baby is bigger they can get better measurements etc, although its not likely to change. But either way your gonna have a baby from the 7th to 25th Jan which is fantatsic. Many congrats and good luck with the pregnancy.



hi im 26 weeks pregnant going from early scan date but going from lmp i should be 28 weeks. i discussed this with my midwife who said i coulve ovulated late and my cycle is usually 32 days not your usual 28 days. i just go with dates from scan now as these are the dates the hopsital use and will go by if your overdue etc. as long as baby is healthy i wouldnt worry bout it too much although it did really annoy me at first as we were trying so i knew my dates, as its only an estimate anyway x
hiya maybe your baby is growing well for its age or you got your dates mixed up, i thought i was due on 28th august according to my last period but when i went for my scan they changed it to beginning sept, i wouldn't worry to much, as long as you and baby are healthy you should be fine xx
Not too sure about your dates mix up but as long as you give birth to a healthy baby, nothing else matters. Dates are just numbers. The reality is that the baby will come when it's ready, not when some nurse or midwife says. Good luck and hope you have a lovely baby
It's based on your menstrual cycle, they count it as 2 weeks BEFORE your first missed period as that is when you are ovulating and will have actually fallen pregnant. You just don't know about it till your period doesn't come on.
You will be given another ultrasound later on and they will measure the baby then too. If she is bigger they will change your due date if not then they won't. Your right though having a positive at 2 weeks is pretty much impossible.
go to babycenter.com and due the dd-prediction based on you Last menstrual Period and take that as your due date.
