<s>[INST] My wife has been advised to take 2 vials of Corion 5000 injection. Today is the 12th day of her last period and she has a 30-day cycle. Her ET is 5.1 (checked today), so the doctor advised her to take 2 vials of Corion 5000 injection today. Is it safe, and how/where is the injection administered?
