I read all this research linking the heat produced by ultrasound (esp. Doppler) to development impact (such as autism) - and I think it is a much clearer connection than 'vaccines' given both the steady increase early ultrasound practice and the steady increase in rates of autism...
So, I was determined not to have any in the first trimester. But then:
A) I started bleeding at 5w0d, and continue spotting till now (8w0d) - scary

my obstetrician requested a dating ultrasound to be done before a formal referral is made. Because of the bleeding/spotting I gave in - did want to make sure it wasn't ectopic at least - though had no pains associated with it. Resulting due date was just 2 days off from what I calculated myself... did see heartbeat though and ensured it's implanted in the right spot!
But now I am concerned... Does it mean my obstetrician will be overusing ultrasounds throughout, if they didn't even accept a referral without it? (Official medical stance on ultrasound is only when medically necessary, with standard of 2 per pregnancy) Should I look into alternatives such as midwife/birthing centre already? The obstetrician had no knowledge of spotting when making that request.
Or should I wait to see what the doctor's approach will be going forward?..
Re: Frequent ultrasound - concerns
Using an ultrasound to confirm dating, non-ectopic status or causes of bleeding during early pregnancy are all legitimate reasons to do early/multiple ultrasounds and does not sound like your doctor is 'overusing' them.
If you are uncomfortable with your doctor, do not hesitate to switch, but coming onto a board of pregnant women with inflammatory/wrong information that could distress others for no reason is a bit alarmist. Also, I recommend changing your screenname so its easier for people to recognize/tag you.

What @kiwi2628 said. Correlation =/= causation. If you're concerned or uncomfortable, certainly feel free to switch OBs. For various reasons, I'll have 3 u/s before we hit 12 weeks, so one dating u/s isn't extreme. Also completely anecdotally, a close friend had an u/s at every prenatal visit with her first, and he was larger at birth than her 2nd son, who had significantly fewer u/s. Neither has autism...
Though a tiny bit dated, a 2004 randomized, controlled research trial conducted by the University of Western Australia followed 2,042 children through 8 years of age and found no long-term affect on speech, language, behavior, or neurological development caused by multiple ultrasounds as compared to those children who only had one.
You can find a “study” on the internet to support anything.
Finally, in the grand scheme of things, having a healthy, but autistic child is not the worst thing.

As everyone else has said correlation does not equal causation. If you are concerned, talk to your doctor about it as well. It may ease your mind to speak with a medical professional.
with DS i has an ultrasound every week or two my entire pregnancy due to being high risk. He’s now a healthy 22 months. I also have a home Doppler that i probably used a few time before i could feel movement. I agree with the other ladies that if you don’t feel comfortable with your doctor don’t hesitate to change. I personally go with what my doctor suggests during my pregnancy because they are the experts and saved my DS. Best thing you can do is advocate for yourself and ask questions, and a second opinion if you feel you must.
With this pregnancy I’ll have one at 7 weeks, then around 12, and then every 2 weeks until I deliver. Because I’m more worried about the effects of profound prematurity than having an otherwise healthy kid with autism. Also from a correlation standpoint, the rise in autism almost perfectly matches the rise in Organic food consumption. Correlation =/= causation.
