For the past two weeks now I have been feeling nauseus.(dont know if I spelled that right) almost like im car sick. Dizzy and sick to my stomach. I did throw up the other morning at about 4 a.M. And had aweful lower back pain. I have these aweful headaches and have been sleeping a lot more than I usually do. Sometimes all I want to do is sleep. I had my last period about 2-3 weeks ago. My husband and I have unprotected sex, sometimes he pulls out and sometimes he doesnt,and im wondering if maybe in pregnant. My last period lasted about 3 days and wasnt very heavy. I went to the doctor and she thinks that I just might be dehydrated. But...I have had plenty of water. Could I be pregant?
