I am thinking I am pregnant. I had my tubes tied in nov 2005 after my twins were born. Toward the end of April 2011 I had my gallbladder taking out and then 2 weeks later had my appendix taking out. They went through my belly button. My last period was may 27. I am never late or irregular unless I was pregnant. I am having all the symptons of pregnancy but I took a hpt this mornig July 9,2011 and it was negative. I then went to my family dr to have blood work done it came back negative as well. Is there any possible way that I can be pregnant and my hcg level just not be high enough to show on the test right now. PLEASE HELP ASAP
