The Novasure System

I had an ablation with The Novasure System (01-16-05) and was wondering if there was any way I could be pregnant? I am just not feeling right. I have taken pregnancy test and they don’t show up positive until after 15-20 minutes and it is VERY VERY light in color (long enough for me to walk away for get and then see in the trash … and wonder). We have not been using protection and I wouldn’t mind if I was but I am thinking I am just getting ready to have a period?

Let me know if you can answer my question.

Thanks
