Hi My name is Amanda, I am 36yrs old and I have been having some pregnancy symptoms which concern me because my tubes have been tied since 12/2011. My last period was 08/18/2015, my breasts have been sore , I have an odd pressure in my lower abdomen, I had some spotting around 09/16/2015, and I have been super tired. I took a pregnancy test about a week ago and it was negative. what should I do?
