I guess, it was my first time

I guess, it was my first time. 

I've told a stranger this, "I have a tattoo. Is that ok? Any problems?"

And the nurse said, "It's ok. It will not affect the test result."

I went through blood test today. I guess, it seemed to be the most complete blood test ever I saw in my life. That 8cc. blood of mine will go through for 55 diseases tests from cardiovascular system to tumor markers. Will get the result within one or two weeks. Aih, nervous. It's a nerve-wracking thing to wait.
