When to Ignore a Negative Pregnancy Test
To understand when to ignore a negative pregnancy test, you need to know how hCG levels increase and what the process in conception actually is. When an egg is fertilized and implants in the uterus, hormonal processes in your body change and start to produce hCG.
That can happen several days after you have sex. It can take as long as six days for the sperm to fertilize an egg, and then it can take as much as two more days before that egg travels from the fallopian tube to the uterus and implants.
It then will take another week or more before the production of hCG is significant enough to register. The fact of the matter is that a home pregnancy test doesn’t mystically look inside of your body to see if an egg has been fertilized and if it’s implanted in your uterus.
Instead, a home pregnancy test measures the pregnancy hormone known as human chorionic gonadotropin, or hCG for short. If you get a negative pregnancy test, it means that you don’t have enough hCG to register on the test.
