Is it safe to have a BBL & BA if I took a Plan B pill 11 days before surgery?

Certain types of birth control pills can increase your risk of deep venous thrombosis and pulmonary embolus.  I generally have my patient's stop birth control that has estrogen or progesterone ahead of time.  I would discuss with your plastic surgeon.  Take Care,Timothy A. Janiga MD, FACS

Congratulations on your upcoming surgery and thank you for sharing your question.  Final results can take 6-12 months for all the swelling to subside.  At our office here at CARE we actually see all of our surgery patients the very next day after surgery and then again at two weeks and beyond. We enjoy staying closely connected to our patients and enjoy giving the extra attention and service. 
Your concerns are important to discuss directly with your board certified plastic surgeon.  He or she will appreciate the open communication and will want to help you. I hope this is helpful and wish you all the very best.  Sincerely, Brian S. Coan, MD, FACS

It is unlikely that the Plan B pill would have any significant negative implication 11 days before your surgery.
Your surgeon or the surgery center it will most likely do a pregnancy test on the day of surgery.
Always share your medical history with your doctor.
Best,
Mats Hagstrom, MD
