What statistical test should I use?

#1
Correlate different time values in plasma of a continuous variable with its concentration in follicular fluid
Hello community.
I would like to ask about what kind of analysis do I have to use for a specific experimental situation.
My sample consists of 90 infertile women undergoing IVF treatment (assisted reproduction) and I have blood samples from various days of the Ovarian Stimulation Protocol (3rd day, 5th day, 7th day, 9 h day and 11th day).
My purpose is to correlate some adipokines levels measured in these samples withtheir concentration in a separate biological sample of the women, called follicular fluid.
Does anyone have any idea regarding the type of analysis I am supposed to do?
Thanks a lot

So you have two different samples of subjects that you want to compare continuous variables between them across time intervals?

No, its one sample of women (subjects) with multiple measurements per cycle ( 5 separate days during their menstrual cycles) and a final measurement of follicular fluid levels.
