I am currently 9 - 10 weeks past my last period. My periods have never been on a 28 day cycle usually 7 weeks apart at the latest. In 2007 I had a tubal ligation after the birth of my last child via c-section. For the past 4 weeks I have been experiencing several symptoms: Sickness (for 1 week), lower back pain (off and on for 4 weeks ranging from minor pain to fairly moderate pain), cramping (like menstural cramps off and on for 4 weeks), mood swings, headaches, and fatigue, bloating, and minor weight gain. I did take a home pregnancy test 3 weeks of go for fear of a tubal pregnancy but it came back w/ a quick negative. I've been told that this could be PMS but is it possible to have PMS symptoms for over a month? My medical history consists of anemia, irregular menstrual cycles, c-section, and tubal ligation. Thank you for any help you can give me. It is very much appreciated!
