Expert Q&A
![]() | ||
| By Linda Given-Welch, CNM Linda Given Welch Certified Nurse Midwife Women's Health Specialists, Chicago | ||
I'm on day 28 of a 30 day cycle and a pregnancy test came out negative. It it definitely accurate?
From the earliest stages of development, the placenta produces hormones (including human chorionic gonadotrophin - hCG) that are excreted in the urine and measured by pregnancy testing kits. False negative tests may be due to dilute urine, or a specimen obtained too early in pregnancy. False positive tests may be due to protein or blood in the urine or the presence of certain medications.
I suggest you repeat the home pregnancy test in one week, and notify your healthcare provider if you have a positive result or if you have a negative result but still feel that you might be pregnant."
