You should talk to your doctor and have a blood test done

Hi, I had 4 negatives and was getting worried as i was 16 day's late with all the symptoms of pregnancy. I was using a cheap test kit. My D/h went out and bought me a clear blue digital test and this turned positive within seconds.

My Doctor told me to wait til next week for a blood test. =(  They don't like to do them unless *really* needed.  So I'm just hoping and crossing my fingers that something happens on Sunday when I take the next test.
