Hi! My last menstruation was last January 30, 2013(first day). Usually my menstruation ranges for 3 days and I have a regular period which is 28 days, am I right? on Feb 15 or 16, I had a intercourse with my BF, not protected . Then on February 27th, I had a very little bleeding maybe just 3 drops of blood. then the next day only 1-2 drops and some small lumps . I think this is my menstruation, but still afraid if I m pregnant.Do I need to take a pregnancy test or not? Thanks in advance!
