<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am twenty six years old and had my tubes tied on December 17, 2009. Around the time the 1st I was supposed to start my period this month, I had spot bleeding, I have not yet had my period. My breast are a little tender and have had some light cramps. I thought that I could be pregnant but took a pregnancy test and it came back negative  <response>: Hello maam and welcome. Please visit your doctor who conducted the surgery and discuss things in more detail with himher, as it is quite clear that your doctor has not informed you anything in detail about pros and cons of the surgery, what to expect and when to report to you doctor. Please schedule a revisit maam, and at the sometime discuss the problem of irregular periods with himher. This might call for a few more investigations, to find the exact cause. Hope this helps. Best wishes.
