I have taken 3 hpt all came up positive, the urine test at the doctor was neg. have had bloods but waiting on the result. am i pregnant?

May be: If your pregnancy test are positive -three times- most likely you are pregnant. It takes time for the body to start producing high enough level of b-hcg to be detected on the pregnancy test kit. Your urine test at your doctor office might be negative as the level of b-hcg was still low at that time and now it is high enough to be detected. F/u with OB and take prenatal multivitamin.
