I'm 36 years old, mother of 3 children & had tubal ligation 9 years ago,however, my body has been showing signs I could be pregnant. In January my breasts were so tender & sore my clothes hurt and that lasted for about a month & then I started with dizzy spells & nausea/queasiness which still happen sometimes at random during these past weeks. I have gained about 5 pounds but feel much heavier, none of my clothes fit and feel like my stomach is so bloated I can't bend & it hurts when I stretch. I'm very emotional like the tears could spill at any second & am having a very hard time sleeping. I took a pregnancy test today but it came back negative and I have not missed a period but I was late in January and march but I still got my period. Help before I go crazy. Thanks
