I am getting married in a few months and I have a couple of questions about my first mikva immersion.

I have a number of body piercings I had done a few years ago and I would like to know if they are considered to be a "chatzitza".

There are 2 categories:

a) Those that I could take out myself. (Eg ear cartilage, navel piercing)
These were pierced a few years ago but I never take them out or change the jewelry as it would cause discomfort and they would possibly close. If I were to take them out they probably wouldn't bleed, but they might close.

b) Those that I cannot take out myself.
I have 2 dermal anchors by my hips that cannot be taken out except by a professional. This is because they have a "foot" underneath the skin with a hole in it that encourages tissue to go through it and thus hold it in place. If I were to remove them, there would be a lot of blood and I would be unable to put them back in.

Please advise as to what I should do. Taharat Hamishpacha is incredibly important to me and I want my mikva immersion to be kosher.
