Nexplanon

it's been three days since i got the nexplanon inserted. My doctor told me to keep the bandage on for 24 hours, i did but she didn't tell me that i had to wait three days to take off the steri-strip bandages so i ended up taking it off myself the same day i took the bandage off. I didn't know about that until i searched it up yesterday. She gave me a paper to read but no where in that paper it talked about that. It's a little bruise and when i try to move it like put clothes on and get something sometimes it stings. It make take about a week to heal i guess, from the other girls experiences but none of them talk about getting their stern-strip bandages off early like me. I put a band aid on and i havent gotten it wet. There's like a green color on the spot they put it in the line shows with the color, i think thats the bruise part. When should i wet it, and should i be concerned about this? I showed a picture of how it looks now.
