Tattoo before/around implantation

We miscarried our first pregnancy in July, and I scheduled a tattoo appt for end of September. My doctor told us to wait 2 cycles to try again, and today I got my positive opk for cycle 1. I know body is still returning to normal, but based on my (loose) estimates, I could ovulate 1 week before my tattoo appt in September, so potentially be right around implantation at the time of my appt. I'm researching about risk of tattoo in very early pregnancy before cancelling this appt, but wanted to see what others opinions and experiences were as well. Thanks!
