Im also a medico in 2nd yr. I am married too for 4 months now. Im 20 years old and I weigh 60 kilos. My period date is around 20th of every month and its usually on time the farthest was 25. I feel really sick and nauseated all the time. I have moved in the beginning of this month to a new place and plus I have exams coming up so is it stress or it could be that im prego? I took the home pregnancy test last week but it stated negative. Maybe I took it early or something? Pls tell me what to look for.
