I think i may be pregnant, i am very nauseous, however I only threw up once, i get very tired while walking up stairs, i have headaches , my breast are very sensitive especially when my nipples are touched, my stomach is getting bigger, and i urinate quite frequently. However my period came irregularly it started off spotting pinkish blood, then after two days it turned into regular bleeding, i tried to Google it and found that it was very normal but it looked nothing like implantation bleeding. i want to know your opinion before i decide to get a pregnancy test .
