Ok I'm 33 years old I have 3 children and when I had my last child 11 years ago I had my tubes tied. Well the last 5 months I have been having these symptoms of pregnancy all of them I have even gained from 10 to 20 lbs I feel movement or like flicker even my husband has felt something I have had a blood pregnancy test it negative and so are the home tests even my breasts are sore and tingling shortness of breath I have a period. My question is could I still be pregnant? I seriously think I am. What should I do?
