Good day! I am turning 22 this year and i am quite bothered with what i am feeling right now. I had sexual intercourse with my boyfriend last January 24, 2009 and that time i was really fertile. According to him, he withdrawed. We did it again on January 31 but he didn't continue releasing some fluid because i was so nervous of getting pregnant that time. I had my menstrual flow last February 2 and it lasted for a week.

In two weeks now, i noticed some brown discharge from my vagina. It really smells very bad. Even if i'm wearing pants, i can still smell it. When i wake up in the morning, my underware has stain. One day, i noticed it became pinkish and thought i'm just going to have my period. I put on a napkin but eventually when i go checked it, my napkin has no blood or stain at all throughout the day.

Also in that two weeks, i am experiencing muscle pain, abdominal pain and back pain. Last 3 days, i am feeling that nausea thing or the feeling of vomiting but when i burp, it sometimes gone. I gained 9 kilos in less than a week. Sometimes i am feeling this pain below my breast and i'm quite moody.

What could this be? Am i pregnant or what? Or just an infection? Help me please... I am now always thinking of these because i dont wanna get pregnant. I am agraduating student now and my relatives keeps on telling me not to do such intercourse yet because when i graduated, i'll be in charge of all the payments and i have big plans for myself and my family.

Thank You.
