I had one at 6 weeks because of a little bit of spotting, and will have one at 10 weeks for genetic testing and again at 20 weeks. I’m a Canadian bee though

I had one at 8 weeks to confirm the pregnancy, I had my NT scan at 12 weeks (which was optional), and then my anatomy scan at 20 weeks. Unless I start having problems that will be it.  The practice I go to switches my appointments between an OBGYN and a midwife.  But my doctor only performed one of the ultrasounds, the other two were at different locations by referral.

I’ve only had a 20 week U/S, since the 12 week one isn’t covered by public health insurance here. As long as things continue normally, It will be my only one.

I had a dating u/s at 8 weeks, check at 12, NT scan at 13 weeks (elective) and am having my anatomy scan at 20 weeks. I expect this to be my last u/s for my pregnancy unless something comes up.

I had one at 8 weeks, 12 weeks, 20 weeks, and my next is 32 weeks. Not sure when I might have the next one or if there will be any more after that.

My ob only does 2 – 8 week dating and 20 week anatomy scan. You can opt to have the 12 week NT scan, which we did. I won’t have anymore unless there’s a concern.

I had 2 from my re at 5 weeks 5 days and 7 weeks. I had one at 10 weeks at my initial ob appt, my nt scan at 12 and another quick scan at 14 weeks due to spotting.  I believe I have one more at 20 weeks (anatomy scan). I also really want to do a 4d scan at some point as well.

So far Ive had my dating scan  at 6w2d (Doctor thought I was 7W3D, and I thought she was wrong)
And I meet with my Midwife for the first time at 12w6d, and the next day at 13w Ill have my second’12 week’ ultrasound, that I opted to get, so we could see our baby and hear the heartbeat again (DH wasn’t allowed in the room at the dating scan, so this will be his first time to see/hear baby) Followed by the 18-20w scan. That will probably be all of them unless I have any problems.

@PARISviaROME:  I’m with an OB. We had an option for one at 12 weeks for screening but turned it down because we didn’t want that screening. We had the 20 week anatomy scan and we had an unofficial emergency scan at 7w with the official emergency one 3 days later. In total we’ve had 3 scans where we would have had only 1 or 2. We may or may not be getting another one near the end depending on how things go (measurements, position checking, etc). I’m at 27w now. 🙂

I guess I’ll find out next week but how to they get the baby’s measurements if they dont do an ultrasound? I hear of a lot of people saying their baby is measuring ahead or it weighs about so many pounds… how do they know?

@SaraP2012:  I hear of a lot of people saying their baby is measuring ahead or it weighs about so many pounds… how do they know?

They don’t, actually. Using ultrasound to estimate a baby’s size/weight is notoriously inaccurate – in most studies, predictions based on ultrasound were less than 50% accurate. This page discusses it (scroll down to approximately the middle and look for “Assumption #2 … Reality #2”).
 
Early ultrasounds can be used with some accuracy for dating purposes, because embryos/very small fetuses all have pretty much the same rate of growth. (The further along you get, the more natural variation there is in rate of growth and the less accurate attempts at dating a pregnancy based on ultrasound become. If your practitioner wants to change your due date based on a later ultrasound as opposed to an earlier one, be skeptical – especially if they are moving the date forward).
 
The other common way to gauge baby’s rate of growth is by measuring the fundal height of your uterus (using a regular tape measure to track the #of centimeters from your pubic bone to the top of your uterus. On average, fundal height rises by about a centimeter per week, although, again, there is natural variation, especially in women carrying multiples).

@MrsSnowPoke:  My OB is the same way. Every appointment I get to see my baby and hear the heartbeat. I find it really reassuring. My pregnancy has been totally normal so far.
