I was 5 weeks along with my first when a blood test showed negative, two weeks later a urine test showed positive and I was sent to the radiologist to find out I was 7 weeks along, I did not register on a blood test because my daughter was caught in my tube, miraculously she moved and replanted, it was very painful...with my second I was about two weeks late when I got a positive test and then this time around I was 12 days late with a positive test, this time the baby was stuck between my tube and my uterus and had it stayed there it could have killed me, thankfully it moved just like my daughter did and I am now going on 17 weeks....I used my first mornings urine every time I tested, I am one of those people who's hormone level doesn't rise quickly, every woman and every pregnancy is different, only time will tell but here is a number to call, Option line 1-800-395-HELP, call and they can give you the number and location of the closest womens pregnancy center to you and you can get a FREE and CONFIDENTIAL test, just hang in there and let us all know...Meg
