Swimming after tattoo?

Okay, so i got a tattoo 3 days ago, (on Monday) and i was curious as to how long i have to wait till i can get in a swimming pool. this is my first tattoo, so i take care of it, and clean it religiously. I take like 3 or 4 showers a day and rub the soap on it that my tattoo artist gave me, and i rub lotion on it as well, as instructed by my artist.. How long untill i can swim? i have heard different answers, so i'm not really sure.
