I can not really give you advice from experience but my doctor has told me that anytime your hormones change (birth control, pregnancy, etc.) it will cause the venous malformation to grow. He has also said that if I were to get pregnant I may want to consider a C-section as the force of pushing will cause it to expand as well. I am curious as to how you are feeling now? I would very much like to have children and like you my malformation is in the right side of my face. Best wishes.
