Pregnancy Info HOME

My last period was on 25th Feb, I did an HPT at a clinic & it shows a faint line, doctor said I'm pregnant. I'm aslo having the symptoms feeling dizzy, food crave, frequent urination, fatigue, abdominal cramp. But yesterday when I did an ultrasound at another clinic, the doc said he couldn't see anything in my womb, he said since I'm about 5 weeks pregnant, he should be able to see it. Then he told me that the urine test I had might not be 100% accurate and so now I have to do a bllod test to reconfirm my pregnancy. I'm feeling so depressed now while waiting for the results, I keep thinking could the urine test be wrong and all the symptoms are just my imagination?
