Ink coming out of my tattoo?

I'm 20 & I got my 1st tattoo yesterday. It's on my right back shoulder & I flippin love it so much. I'm so happy I did it. They told me to put Aquaphor healing ointment on it for 2 weeks & keep it out of the sun.I'm a bagger/cashier so I'll be in the sun a little getting carts. Plus I live in Florida. It's hotter than a ***** outside.. I was wondering if I should cover it with a bandaide? would that take the ink off?? cuz this morning when I was taking a shower I covered it with a bandaide when I took it off there was black ink. I don't know if it's from my tattoo or just the rest of the outline?
