How long had you been on the gel? I'm not familiar with it, but isn't that a fairly high dose? Firstly, I wouldn't change anything until you're well clear of your infection and have had time for adjusting to Mirena. But then I would wonder if the estrogen is too much. I'm sorry, I don't recall your history. I actually asked about the estrogen because that described how I felt before estrogen, but as I'm sure you know, the symptoms of too much vs. too little estrogen are very confusing and overlap. Hang in there! I hope you're feeling some relief soon.
