Hi. I am 17 and started my period on the first or second of March. It finished between the eighth and tenth of March. I had sex on the fourteenth of March. My period came back on the fifteenth which is too early as my periods are usually seven days once a month. My second period went from the fifteenth to the eighteenth which is shorter than my usual period. On the nineteenth of March, I had very light bleeding which stopped. I'm just wondering if it is possible that I could be pregnant. Any information would be greatly appreciated. For the past two days, I have been feeling extremely tired (more tired than usual), tender breasts, bad headaches, dull pains in my lower abdomin, have increased salivation, nausea which seems to get a bit more unbearable every day, avoiding favourite foods and drinks and eating things I usually can't stomach such as fish. I have become noticeably more moody, have a kind of metallic taste in my mouth and even water tastes different. Last night, I was cooking dinner when I had a huge wave of nausea hit me. I had the sudden thought that I may need to run to the toilet to throw up. My period is due early next month and thinking of buying a pregnancy test on Friday which is the twenty-fifth of March. Is this too early to test?
