I am 21 years old,I forgot to start taking a new pack of contraceptive pills this month, period was supposed to arrive may 7th, had light brown spotting may 10-14 (started taking pills on the 10th because I thought I started my period),I have no symptoms at all except for spotting, took a pregnancy test on the 15th, came back negative, now I have clear discharge with brown spots, am I pregnant?
