This varies depending on your insurance, country, OB, and risk level (e.g. high risk PG vs low risk PG). Oh, and if you did IVF, that gets many more US initially.

I personally got:

– 8 Weeks (vaginal/routine)

– 12 Weeks (NT scan/technically optional)

– 20 Weeks (Anatomy scan/routine)

– 31 Weeks (this is extra because I measured large at my 29w appointment)

and I’m expected to get a 36w US which is also considered routine for me.

As far as I know, my OB categorizes my PG as low risk.

It varies.

I had one at my first prenatal appointment (11wks) because they could not hear the heart beat.

I had one at 13 weeks for the nuchal translucency (this is an elective screening test).

I had the anatomy scan at 18 weeks (usually at 20wks) but they found a cycst in the brain that could either be a completely normal developmental thing that we happened to catch or it could mean there are other severe, life-limiting birth deffects.

So, I had 2 repeat u/s to check up on that situation.  (Everything ended up being ok)

I had a non-stress test at 40w since it didn’t seem like I was going into labor anytime soon and they have to check the amniotic fluid level.

I think I would have only had 2 or 3 total if: they had heard the heart beat at the first appointment, there hadn’t been a cyst, and I hadn’t gone over due.

Here, there are two routine ones at 12 and 20 weeks. But I had an extra one at 8 weeks.

My doctor seems to like them at every appointment. I’m low-risk and baby is progressing just fine. It might just depend on your insurance as well. 

I’m 15 weeks and have had 3 already… One at my 9 week appointment (first OB appt) another at 10.5 weeks before I went on vacation (doctor couldn’t schedule me later due to my trip and his vacation after) and my 3rd at 14 weeks.

I have another appointment at 18 weeks. The technician said we’ll probably be able to see the sex of the baby then.

I’m beginning to feel pretty lucky that I get to see baby each month. I am surrpised that his office does them far more frequently. Do you hear the heartbeat at each appointment if you dont get an ultrasound?

I’ve had quite a few.  I had a miscarriage previously, and bleeding during this pregnancy so I got early ones to check that out.  I’m also higher risk right now and my insurance covers me to have ultrasounds every 2 weeks in the 2nd trimester.  After that, I will only have more if I need them for other reasons. 

So I had:

5.5 weeks (in hospital for spotting)

6.5 weeks (at doc because spotting returned)

12 weeks  NT scan

14 weeks

16 weeks

18 weeks


Will have:

20 weeks (anatomy scan)

22 weeks

24 weeks final checkup for 2nd tri issues


At my doctor, you get to hear the heartbeat every time whether you have an ultrasound or not.

Definitely depends on a few factors. I was seeing a fertility clinic, so when we got pregnant we were given an u/s at 7 weeks to check for a heartbeat.

After that, we did the 12 week NT scan (this was optional mind you for the early testing and the requisition was through our midwife).

We also had the 20 week anatomy u/s.

Due to a previous history of some kidney troubles, my midwife sent us for a consult u/s at 22 weeks (a placental study to assess maternal risk) at one of the top hospitals in the city. The consult cleared us to continue with our midwives and deliver at our hospital of choice, but we do have to do 2 additional ultrasounds at 32 & 36w to check on baby’s growth and make sure everything is still on track.

So – we are definitely the exception rather than the rule… we will have 6 in total by the time we hit 36weeks. I think “normal” is around 2 (12 week if doing the testing and 20 week anatomy scan)

We had the 12, 20 and 40 week ultrasounds.  I opted out of anything optional since US side effects are still questionable for baby.  Our baby shies away from the US when its on it.  That to me says US use should be limited.

@christinamarie980:  We still check the HB at every appointment if there’s no US. They use the doppler instead.

@pittgirl4:  Usually 2-3 depending on your situation, your doctor’s protocols, and any complications.  12 weeks for heartbeat and 20 weeks for measurements (and sex!) are usually pretty deifnite.

In countries other than the USA, there tend to be fewer US since they really aren’t necessary and there is considerable evidence that they could actually put the baby at risk – reducing exposure is always a good idea. The elective 3D ultrasounds that are so popular here are definitely not all the rage elsewhere for that reason.

In Canada… like one at 20 weeks (anatomy scan). Sometimes one earlier to date if you didn’t know when you conceived.

If you have complications, you’ll likely have many many more.

There is only 1 routine ultrasound offered here (in Qc) at 20 weeks. A NT is offered at 12-14 weeks for women over a certain age or that have had previous pregnancies with generic defects.

@pittgirl4:  well I’m only 7wks pregnant and I had one ultrasound at 6 wks because I didnt know when I concieved, and will have another one tomorrow because heart rate was a little low. Then if everything goes good I think i should just be getting two more thruought the pregnancy one of them of course to figure out the sex! That makes it 4 ultrasounds for me 🙂
