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 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.
