Are ultrasounds accurate please help

[moongem1]

Hey guys I need help knowing how accurate an ultrasound is....?
When I first found out I was pregnant I was told I was 7 weeks, the doctor told me to book my 11-12 week ultrasound and as told I did. When that time came the ultrasound stated I was only 5 weeks pregnant.. I was told to book another one for 6 weeks time to get a better look, after those 6 weeks I went back and it showed I was 9 weeks (it doesn't add up to the amount of weeks I waited) By this time I already had 2 different due dates. I then waited 11 weeks for my 20 week ultrasound it then stated I was 18 weeks along with a different due date again! I'm very confused the amount of weeks I wait between each ultrasound don't add up.. My last period date was the 7th of march should I go by these dodgy ultrasound dates or my last period date?? Please help

Ok thanks it's just so confusing I just want to be prepared! All these dates have a good distance in-between them! I'm gonna try another doctor and hopefully get another ultrasound!

Also after about 12-14 weeks babys start to grow at different rates so any due date after that point that they give you won't be as accurate. Some will measure behind, right on, or ahead. I am 19 weeks and my baby is measuring right for her length but is measuring big for her estimated weight. So it just depends on the baby as well :)

As long as baby is growing and has a strong heart beat I would not worry about what your due date is. Baby will come when it is ready.

Since I was seeing a fertility specialist for the beginning of my pregnancy and am now seeing my regular ob, not all of my ultrasounds were sent to my ob he is unsure of what my due date is, but I have to have an early c section due to a weak spot in my uterus and if I go too far it may rupture.

A week or so is normal, but it may have been to not having a very experienced person performing the ultrasound or outdated equipment.

I have Jan 9th 15th 28th and feb, in early April I had a bit of blood but it only lasted a night and it happened after sex so I just assume it was because of that... I dunno what to do :s

My last period when I got pregnant with my daughter was Mar 3, I had her on Dec 7, with a due date of Dec 9. When do they say your due date is? Have you talked to them about the changes in dates?
