Hello, my name is Kori (hence my screen name) any-who, I am 22 and a single mother of one adorable five year old boy. Well I started dating an old acquaintance of mine from my teen years. Well, for the past six months or so we have been sexually active, well starting in March my period was extremely light; almost like pink water. well in April I didn't have a period. May was light exactly like March except for the last two days which was a gush to normal period. Then last month was a no show on my monthly again. I have been sick to my stomach every day in the afternoon and evenings for the past few weeks. I have also been getting headaches more often. certain smells and foods just turn my stomach. I have also experienced slight cramping and dizzy fits when i just sit there watching television or im standing somewhere talking. I have also acquired a butt load of heartburn and back pain. I have taken a home pregnancy test, which was in the beginning of May, but that was negative. I also saw my dr and took that test, that was also negative. I am also a student in college online, but I am not under any stress, I would know if i was, because I have a five year old and a house to keep in order. oh...almost forgot to mention that all i want to do is sleep, but have a hard time sleeping more than maybe 4 hours at a time.

can someone give me advice?
