Essure procedure

Ok this may sound a little crazy, but oh week here it goes, I had the essure procedure done after my 2nd child. My husband and myself decided since we had 1 boy and 1 girl we really didn't need or want anymore children. About a month ago some friend and I went to see a psychic on a girls night out. She told me I was going to be a mother of 3. I explained to her that couldn't happen, but she said honey it will by the end of this year. Which is fine with me lol and my husband actually we aren't against having 1 more, we just were not in a financial situation 8 years ago to risk having another child and birth control has never been an option for me, my body doesn't deal with it. So I decided to download the app just to see what my ovulation days were and so on. Well somehow this month I had 2 periods which is really odd. Any thoughts???
