What Blood Test Can Be Affected By Me Taking Primolut

What blood test can be affected by me taking Primolut N? I am using it to bring on a bleed as I do not bleed by myself. I need to bleed to start Clomid for ovulation as I do not do that by myself as well. Obviously the desired outcome is for me to beable to conceive. I have a long history of PCOS and Hyperplasia.

I need to get basic blood test done for iron studies, glucose, B12, Liver function test, FBC, Lipids, Cholesterol, Vitamin D and TSH.
Can I still take Primolut N or should I wait and have the test done first?
These test are part of a weight loss program that I am completing and need to have them done in the next few weeks. So if Primolut does effect the test results, how long should I wait?
