so in the beginning of january i got pregnant but was bleeding 3 weeks into the pregnancy i went to this clinic they did a pregnancy test but came back negative. they said i most likely had a miscarriage so i was like ok... but i still haven't had my period. it should've been here by now. i haven't had it since december. is there a possibility that i could still be pregnant??? has anyone ever had pregnancy tests come back negative but you knew you were actually pregnant?????
