.I am 19 years of age . I haven't had a period since February the 19th . I've taken 3 home pregnancy test but everyone of them came out negative.  I've been very tired and nauseated. I have been having slight period cramps but no period. Should I be worried?  Am I pregnant?
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. As all your urine pregnancy test kits gave negative results the possibility of pregnancy is less. Tiredness and nausea can be seen in other conditions like premenstrual syndrome, hormonal imbalance etc. To be sure, please go for blood test for pregnancy once. If test gives value below 5 mIU/ml, the possibility of pregnancy is almost ruled out. In that case, you can consult your doctor and take tablets for withdrawal bleeding. Hope I have answered your query. Let me know if I can assist you further.
