<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am getting my Mirena removed next week and I am wondering if the removal of an IUD causes ovulation. I am wanting to get pregnant as soon as possible and need to know what the chances of an immediate pregnancy are. I have had my iud since April 2011 and have only had one period while it was in place. I havent had any problems with the iud.  <response>: Hi, IRENA is not a simple IUD. It has hormones impregnated, which were entering your body suppressing your bodies hormones. It will take some time for your body to start the regular cyclical hormonal production. Usually within a month or two you will have normal hormone levels, so normal ovulation. Usually after such suppression body hormone show a surge suddenly good number of follicles start growing pregnancy chances are good. Hope I have cleared your Doubtful the best Chat Doctor.
