so i’m a week late to my period.

had unprotected sex with my boyfriend on 2/18, 2/19, and 2/20 and i took a pregnancy test today (2 weeks since we had sex) and it came back negative. i also took 2 other pregnancy tests on 3/3, both of which came back negative.

i’ve been having light spotting (that started on 2/23 and is still happening) cramps, breakouts, and backache. i was stressing all of last week thinking about whether i was pregnant or not (now i’m not stressed), and then got sick on 3/4.

if all 3 pregnancy tests came back negative, why is my period late?
