I accidentally got my eyebrows wet in the shower in the first few days, could I have ruined my results?

During the first two weeks it is important to keep water off the area.  I usually recommend putting a layer of vaseline on the treated area to help repel water.  There is a good chance you will be okay, but from here on out use the vaseline and only dab the area with a cottonball to reduce the chances of losing pigment.  You can apply grapeseed oil to the area to keep it soft.  You will know if you need more pigment put in when you are 4-6 weeks out.  It is too early to know now.  If you do need more pigment placed on your brow,  it is easy to just put the missing lines in.
