i missed my period 2 weeks ago, until now there s nothing coming out yet. i can only notice increasing dirty yellow to light brown discharges. 2 days after missing my period i had a negative result of pregnancy test so i decided to take my routine chest x-ray every year, a week after that missed period. then i had a pregancy test again and pelvic ultrasound. the result is negative preg test. pelvic ultrasound result turned out normal with thick endometrium suggesting early pregnancy, or a menstruation coming. but i had the preg test again 10 minutes ago and it turned out positive. i m worried and don t know what to do. after all those chest x-rays and experiencing mild-moderate lower abdominal pains near my pelvis. at first i ignored the pain because i thought it s just premenstrual pain. but after the positive preg test, i so worried already. i m not married and still don t have plans of having a baby.
