Hi,I'm currently 21 and my boyfriend and I have had intercourse many times without using some kind of contraception.My question is,could I be pregnant?I took a home pregnancy test after the first time and it came back positive but when I went to the doctor and did a urine test,it came back negative.The doctor told me to wait until I thought I was 2 and a half months pregnant before taking another test because he said that if I was having the symptoms,there could have still been a possibility I am pregnant and it's just too soon to tell.Well,lately I have been having what my parents call morning sickness but I never throw up.I'm just constantly nauseous and I almost throw up.It happens every day... lasts almost all day and even when I get hungry,my appetite has changed dramatically but then I start feeling like I'm going to be sick again.I get upper leg cramps at night and I've had headaches every day.I feel tired,I have lower back pains that almost feel like what I get before I start my period but not quite as severe.A friend thinks the cramps could be implantation but I'm not bleeding at all.I lost a bunch of weight but now,I'm gaining.I still have to wait 3 more weeks for my period to arrive but I just keep having the feeling that I am pregnant.Every thing I have read about pregnancy symptoms I have almost all of them except for the missed period.What should I do?

If you have not missed a period then there is not much you can do other than wait to see if your period comes!! If it doesn't take a hpt with your first morning wee if this still comes back negative go to the doctors and ask for a pregnancy blood test!!
When was your last period??
