i think i may be pregnant. For the past two and a half weeks i have been nausea and vomitting and off my food. I cant stomach food til 3 pm and then its not much. I have been suffering from headaches and heartburn which i never have before. My breasts have gotton fuller and heavy and my stomach is noticably fuller and feels heavy and firmer. I have put on weight about three kilos in the past months. I walk for an hour a day. My nose will run for no apparent reason and i dont suffer from allergies or have a cold at present. The last time i had sex was feb 13 and it was several times and unprotected. What i thought was my period arrived feb 22 it lasted three days and was very light mainly spotting. On march 6 i spotted for most of the day. Actually my last two periods have been very light and lasted three days where normally they last five days and are of a moderate status. I have been with my partner for five months and we always have had unprotected sex. Do you think i can be pregnant? I took a home pregnancy test march 12 it was negative.
