My husband and I had 3 failed IUIs and we are on to IVF. We did a saline sonogram today and the doctor said I have a very tight cervix. He said I will need to be dilated prior to the IVF (in vitro fertilization) transfer. They will be dialating during my egg retrieval since I will be under anesthesia. Has anyone heard of this or had this done? I’m really hoping it helps my success for IVF. Any insight is appreciated!
