How soon after breeding is the earliest that a mare can be checked to see if she is in foal??

I've been told two different things: 14 days and 16 days. [My vet is planning to ultrasound in 16 days] Hope this helps!

The mare can be checked by ultrasound as early as 10 days, but the general practitioner will not be likely to check until about day 14 at the earliest as a matter of routine.
Horses should be checked at day 15 and day 28 for twins, as if adjacent twins are detected at day 15, they are still in the mobility phase and will be likely to have moved after about a 15 minute delay, allowing easy manual reduction. Checking again at day 28 prevents missing a twin pregnancy if there was an "asynchronous ovulation", or in other words, 2 ovulations several days apart which might result in (for example) a day 10 and day 15 conceptus being present on a day 15 check, with the [very small] day 10 conceptus being missed.
Ponies should be checked at day 14 and day 28 as the conceptus generally becomes fixed in ponies a day earlier at day 15 rather than the day 16 seen in horses.

How should I count the days? My mare was bred on the 21st and ultasounded the next two days and found to have ovulated on the 23. This assumes that she ovulated on the night of the 22nd or early morning or the 23rd. Is the 23rd day 0 or day 1?

Day 0.
