Subjectivity or Construction ivism?

A

I'm just writing down my Research Paradigm employed for my research, however I am really confused between these terms
Subjectivity
Constructionivism

Are these both paradigms? or epistemology? Also, what is the difference between the two if there are any?
I' dont want to end up writing down a wrong research paradigm.

My research is qualitative based - but the overwhelming array of terms baffles me. thank you.
