Is this what is called stretch marks?

Krl • Blessed with an amazing 3yo, and his 2 little brothers (mono/di) since November! My boys 💛🧡❤️

So this is my belly. I prefer to state it because it looks weirdly like a big nipple, but not, just my 35w stretched belly with twins :)

For my son I never had stretch marks so I don’t really know what they look like.

From this week I have these little purple spots or really tiny stripes. When I press my skin around, they lose their color and look like small depression in the skin.

Is this how stretch marks start?
