 Posted: 06/02/05 - 02:00 Post subject: How common is a false negative HPT? |
  |
|
Hello. I’m 18 year old female. I have a boyfriend for over than five months now and recently I have started sexual relationship with him.
He is very good to me and he cares about me, so I don’t have any reason to not believe him.
He is very careful and we used condom every time we had sex.
A week ago, after one party we all drank a bit and after it we had sex but he didn’t use condom.
After two days I started to experience symptoms of possible pregnancy.
I felt nausea, tender nipples and feeling sick almost all the time. You couldn’t imagine how frightened I was.
I ran to one drugstore and bought one home pregnancy test, used him and results were negative.
How common is a false negative pregnancy test and what causes it?

Whether it's your first time or your fifth time, taking a home pregnancy test (HPT) can be frustrating as hell.
Today’s tests are very accurate and most home pregnancy tests claim to be 97 percent to 99 percent accurate if they're used correctly.
So the basic thing is to use them properly.
Home pregnancy tests determine pregnancy through the detection of the hormone Human Chorionic Gonadotropin (hCG) in a woman's urine.
There are several possible causes of false negative pregnancy test.
If you take a home pregnancy test too early, you may get a false negative result.
Also, if you hold it too short in your urine stream you could get false result. Consuming large amounts of fluid before taking an HPT may also cause a false-negative test result because it has diluted your urine. It's best to take an HPT first thing in the morning because that's when your urine is the most concentrated.
If the home pregnancy test shows negative results but you still think you could be pregnant, wait a few days and try again.

| Your main cause for negative test is that the HCG (hormone) levels can be low, home pregnancy test sometimes needs a high MUI level to detect the hormone. You can always confirm with a blood test if you haven't gotten your period and still worried that you may be pregnant. |

"Just because you did not have symptoms that early, does not mean you should misinform others. I had sex on Saturday and was having symptoms on Monday. My boyfriend was making jokes which I totally blew off because I ABSOLUTELY DID NOT THINK SYMPTOMS COULD APPEAR THAT SOON! Well, by Wednesday I had severe shooting pains in my lowere abdomen, in addition to other symptoms which included and increased appetite already. I took 2 home pregnancy tests which both had positive results, all within just 4 days after intercourse. What a surprise this was to me because I thought just like you do about this subject, did not know it was actually possible to get any symptoms this early. But boy was I WRONG! |

Well, the morning after i supposedly conceived i woke up telling everyone i was pregnant, and didn't find out with a test for another month and a half.. The doc said i was accurate with timing and everything, and that i was most likely right about the feeling. If you know your body well enough, you can feel the hormonal changes taking place. I'm young but i know my body. |

|

| In response to Montana's statement that you can't feel pregnancy symptoms as early as 2 days.....you certainly can!!! I felt my first symptoms 4 days after trying to conceive. I was sick to my stomach and had breast tenderness, headaches and severe fatigue all within 4 days but with my first baby I wasn't sick until I was 8 weeks preggo! It all depends on how sensitive your body is to the hormonal change. |
