I did not, although I have gotten a severe headache with doses above 20mg. (Actually, I can get a dull headache at 20mg also.) Since I rarely get headaches and having a severe one for three days in a row is unusual, I am reasonably sure this was a real side for me. I did not notice any others. Everyone is different.
Also remember that the "target market" for this drug is women undergoing cancer therapy. It is somewhat risky to draw comparisons between the common side effects and what a bodybuilder would expect during PCT.
