My breasts have been sore all over, especially my nipples ,for the past two weeks. My husband and I were scared that I may be pregnant, so i took a test. It was negative, however, my period missed away and my breasts seem to be getting bigger and hurt worse everyday. I have gained 7 pounds in the last month and feel very exhausted for no reason.(April 2nd is my last mensural circle and we took the test on may 11th).Nowdays sometime i feel like a metal taste on tongue ..and sometimes feeling tired.. Should I take another pregnancy test? I know that some women still have their period during pregnancy. How common is that? I do not have health insurance right now so going to the doctor is out of the question. Any help would be appreciated. Thanks.
