I am 18 years old and i got intimate with my boyfriend last month. I got my period on 3rd February, and since i took an ECP after having intercourse, i had some bleeding for about 3 days on 16th of february. I am not sure if they were periods, but if it was, then i was supposed to get it by the 16th of this month, but i still haven't got them. I have taken 2 pregnancy tests but both were negative. What should i do? Am i pregnant? Please help.
