I am 30 years old. I have three children. My oldest is 12 years old and my youngest is 3 years old. I am divorced. I got a tubal ligation in Feb 2007. After I had my last child. My period was coming whenever it wanted to, but it was coming every month. One time it even came twice in one month. When I got pregnant with my last child I found out at 3 months. But I got my period all three months before I missed my period and took an at home pregnancy test. When I went to the doctor I was feather along than I thought I was. I am now engaged to a much older man. He has a child of his own, but his child is now grown in 20's. My fiance wants another child. With me not having any money to get this thing reversed, I wanted to know if there is a possibility to get pregnant again. Now I am starting to want just one more baby. I think it is because a lot of people I know are having babies. A few times I thought I was pregnant, but when I would take a at home pregnancy test it would always come out negative. I was told that my tubal ligation couldn't be reversed. Lately I have been feeling like I am pregnant, but when I take the test they always say negative. For the last few months my period was coming on the 28th of each month. Then two months it came on the 20th, last month it came on the 15th. I have symptoms of pregnancy and I have had 4 mood swings in one day. I never had that before. I even have a little bulge in my lower stomach. Could I be pregnant, or is it just my imagination?
