Third week bleeding on an unknown miscarriage and my BA surgery is on Monday. Will I still be fine to go through with it?

If you are worried, please call your surgeon immediately. We surgeons are here for our patients not just medically/scientifically/aesthetically, but emotionally. I know that if you were my patient, I would want to speak with you to help you during this stressful time. It pains me when patients wait to discuss something with me they are worried about, because I can always help them with their worry. So please, call your surgeon now.  Don't wait until Friday afternoon! 

Please call your surgeon. We are all different in how we handle this. You may need to provide some information specific to your case. You will find the office nurse to be invaluable and I suggest you start there.

Greetings.  Just be patient to get the results of your blood work.  Some physicians will not do the procedure without some type of clearance from the OB/GYN and/or the labs showing no evidence pregnancy, even with a miscarriage.  Discuss the options and results with you physicians and plastic surgeon.  Best wishes.

Please discuss this with your surgeon. If there is any chance that you are pregnant, the surgery will need to be cancelled. You do need to wait on the blood test. It might be safer to postpone your procedure.
