I'm nervous and hoping someone had this experience....today I had my preop stuff done at the hospital to include blood work, EKG, etc. All results are good. as I left I was provided with preop instructions very similar to what my dr had provided in my last office visit last week except it also stated to stop birth control 2 weeks prior to surgery. My dr never mentioned that but is aware I take them. I was not taking the pill at all last week because it was my time of the month, but I did take them the first four days of this week. I'll stop today but my surgery is this Tuesday...in 5 days. I'll call my dr in the morning to get his thoughts but can't get it off my mind and don't want to postpone anything. I'm healthy other than overweight and sore knees. Anyone had a similar experience or thoughts on it? I'm just thinking about blood clots and other things that the pill puts me at risk for...doesn't help that it's YAZ
