Hi, I had sex 30-35 days before. I had i-pill within 4-5 hours. After 2-3 days I got withdrawal of two -three drop of blood which can be withdrawal bleeding (i don't know what exactly it is). I dint get my periods till date which may be because I have my exams soon. Due to which my physical movement is almost nil. And also I had urine pregnancy test 2-3 times (once in morning too )it is negative all the time. I want to confirm is it pregnancy or because of stress n no movement only. Also my left arm is numb from 2 days and I am feeling to pee frequently. please tell can I pregnant or what. What should I do.
