In August 2014 I had my tubes tied after having my son, however I have missed my last 2 periods, my breasts are leaking, I ve gained quite a bit of weight and am having mood swings. I ve used 5 home pregnancy tests and only 1 showed a positive result. I am also on methadone, baclofen, and gabapenten, for chronic pain, as well as kilonopin, mertazapine, ambien, and seraquil for ptsd and other mental health issues. I don t know what to think, could I be pregnant?
