First of all, PMS indicates nutritional deficiencies, so I would go to the health food store and ask the vitamin person what they recommend. Second, I have had the Mirena since January, love it! I spotted at first but now I don't get my period anymore, and haven't since June, PMS ended then, too. I feel great. As far as the fertilized egg goes, I talked to my midwife, and she says they don't know for sure, but no one she has talked to or heard of believes that fertilized eggs are lost. So I decided to believe that. I have been gleefully giving away and selling my baby stuff. So happy to be able to move on and not look back. We decided not to do a vasectomy because it can cause a man to lose his drive - not just sex drive, but ambition.
