I am getting a tattoo in two days and need help. Does this translate into what I think it does?

तवस् सत्कृति करुणा

It's impossible to know if this means what you think it means without knowing your thoughts.

There are a number of free (or low charge) translation sites available.

It appears to be Hindu,

At least my translator says it has some Hindu characters in it,

As with most, as I learned very well, are never exact to English, example here in China there are 1000's of English words that have no direct translation, and 1000's of Chinese words that have different meanings depending on usage.

But for what it is worth here are the two basic translations

Satkriti Compassion

Tws Satkriti Compassion

Or when corrected for translation

Twas Sanskrit Compassion

I am told it means tops, kind treatment or good action or virtue, kindness or compassion.

I don't know if this is what OP thinks it means.

"Remember to drink your Ovaltine"

Now, is that the translation or what the OP thinks it means?

I'll go with the translation.

It's sanskrit, means ,devoted good deeds and kindness.
