Last month i was 6 days late for my period. i took a pregnancy test and it came back negative, the next day i started my period, in the middle of the day which never happens its always first thing in the morning and usually very heavy! this was light and gradually got heavier and lasted 6 days again not normal. 2 weeks ago i started getting quezy but havent had any other symptoms untill this morning i actually thew up after taking a vitamin, i took it on an empty stomach? which i always do and have never gotton sick before today! i literally have taken 2 negative pregnancy tests, and have no other symptoms. i have 2 other children and during pregnancy i literally had no morning sickness, no br___t tenderness nada zilch! so my question is am i or could i be pregnant?
