If you brewed from an extract kit use the original gravity the kit says. In 12 hours the test you might take would no longer be valid as fermentation would have already started as the yeast would be building up their numbers. In 24 hours any sample you would take would give you a wrong answer.
Unless you really need to know the ABV of the finished beer, just wait and take a couple FG readings when the ferment is over to verify that the readings are not changing. If they match exactly, you are ready to bottle.

Too late now. If it was a kit, you used all the ingredients, and got the right volume the predicted OG in the instructions is going to be close. And as close as you are going to get now.
As to the OG, if you do not care to calculate for the ABV, you don't really need it.

Grab me another beer please!
When I did my first few brews, I don’t think I took any readings. Was more concerned if I made beer and if it tasted like beer. And getting the steps right, cleanliness, etc.

FYI many "kits" are all grain.

My first beer was from an all-grain kit.

True, but most (I know, not all...) first time brewers tend to go with extract kits for the first few times.FYI many "kits" are all grain.

I forgot something too.... To add the word extract in front of the word kit.
I wanted to point out to a newbie that brewing with grain isn't so scary.
It's all good.
Get that, but with all grain the "go by the predicted OG in the kit instructions" goes out the window. Still if the brewer doesn't really care about the ABV, an OG reading is not totally necessary. But if the brewer wants to work on consistency it is.
If you happen to have a refractometer you could get a pretty good estimate on the original gravity. Once the beer has finished fermenting, check the FG with the hydrometer, check the Brix with a refractometer and plug those numbers into a "OG of finished beer" calculator. I've had to do this once before and used the one on Beersmith.
IMO, this will give you an estimate of the OG, how accurate is questionable since it is a calculation based on a couple of SG readings. There will be error there as well as in the calculations. How much error? I don't know.
