I got pregnant 10 months after having my tubes tied. When I was suppose to start my period I was having cramps. It just felt like I was about to start anytime. I even had spotting six days before I found out that I was pregnant. My second and third child are 19 months apart. At first my husband and I were shocked, but then we accepted the fact that the child was meant to be. Well after the last was born I had a partial hysterectomy. I had some other issues going on too. Good luck with everything.
