I don't want to discourage anyone who might want to use this type of birth control, but I found out yesterday that the bout of "flu" that I had a few months ago was the harbinger of a brand new pregnancy. I have 2 children already and 16 months ago, I had a full surgical tubal sterilization (ie. the tubes were cut and cauterized) during a Cesearean delivery. According to the doctor, this is the most effective way to perform the procedure and has an incredibly low failure rate. During the post-delivery clean up when my doctor was tying the tubes, he was incredibly distracted as he had several interns to supervise and one of them had given someone in labor an incorrect dose of medication. I remember thinking "I hope he doesn't screw this up!". I am not kidding, during the actual procedure I distenctly recal having a premonition that it was not going to work. Of course, at the time I wrote it off to the morphine! WAY back in December of this year I had a month-long bout with the "flu" I did not use a home pregnancy test as I should have, although I did discuss the possibility that I might be pregnant with my doctor's nurse. She told me that there had never been a patient in their practice with a failure of a tubal when it had been done the way mine was. So, I ignored my gut (ha ha) and after a few weeks I felt better and let it go. Flash forward to two weeks ago, my husband got a good look at me in the nude and commented that my breasts were really getting huge. In fact, I had put on about 15 pounds but had attributed it to be a stay-at-home mom stuck inside with kids all winter. My first phone call to my doctor was about a week ago, after lying in bed and being positive I could feel movement. His response was that it was "gas". I'm only 23 and I'd like to hope I don't have that particular issue just yet!. It took an entire week of pestering, but i finally managed to convince a sympathetic nurse-practitioner at the practice that I NEEDED to come in for an ultrasound. Sure enough, I am expecting a baby girl in August. I am over halfway through my pregnancy! I'll keep you updated!
