A false positive pregnancy test is when the test says that you are pregnant but actually you are not. This is a one off case and a positive pregnancy test is a pretty good indication that you are pregnant. False positive pregnancy tests are rare - though there are instances and conditions where they can occur.
There could be various reasons for a false positive test.
Chemical Pregnancy
A chemical pregnancy is basically an early miscarriage. Research has shown that half of all first pregnancies end in miscarriage. Due to the high sensitivity of home pregnancy tests, many women catch early pregnancies but end up going on to have their periods due to a chemical pregnancy.
Missed Reaction Time
For accuracy in home pregnancy tests it is essential that you read the test results in the stipulated reaction time. If you let the test sit for too long (after the instructions on the box tell you), the test is invalid. This may cause it to show false positive results.
Chemical Interference
Drugs that have the pregnancy hormone Human Chorionic Gonadotropin (hCG) in them can cause incorrect results in home pregnancy tests. The Human Chorionic Gonadotropin (hCG) in them may be responsible for the false positive pregnancy test. If you have had an HCG shot due to infertilty treatments, you need to be sure the shot is out of your system before you attempt to use early pregnancy tests.
Evaporation Lines
While technically not a true pregnancy, some pregnancy tests leave a faint evaporation line as the urine crosses the test. This faint very light grey evaporation line in the test area is often interpretted as a positive result.
AimStick pregnancy test strips have a very good reputation of NOT leaving evaporation lines and are much less expensive than brands you can buy in your local supermarket or drug store.
If you are not sure about your home pregnancy results it is recommended that you try again after a couple of days. If doubts regarding the results still persist, you must see a doctor for a pregnancy blood test. A blood test administered by your doctor is more sensitive than the early home tests and can be taken between seven and twelve days after you conceive.

My home pregnancy tests were instant ositive....but my Dr said that I only had a "slight" positive with the blood test. He also told me at 7 weeks that my baby was too small according to the ultrasond and that it probably stopped growing...I switched doctors and had a whole series of blood work and a new ultrasound. My baby is fine and everything is normal.....Sounds like you need to switch doctors to someone more positive......oh, by the way: go get a book called Taking Charge of your fertility by Toni Weschler. It will help you understand your body and all the myths about it. It will help you time when you are ovulating and the best times to conceive. My Doctor recommended it to me and after 1 year of trying I got the book. It worked the very next month. It turns out that my timing was wrong due to mis-information. I hope it helps you, too! It's not only about getting pregnant. It's about knowing your body and knowing when you are fertile or not. You can pick and choose what you do with your info. Good luck and don't listen the all the myths!

you know it could of been some kind of medication that you were taking or something like that. I took a pregnancy test once and it came back pregnant and then the next day I woke up in a pool of blood. So I don't know if your body like naturally has some kind of hcg in it or what! It's crazy. I'm sorry to hear about your misleading results. It'll happen though! Good luck

I have had blood pregnancy tests done 8 times (i have had 5 miscarriages) and they were all positive and they were correct. The doctor usually does a follow up check if you get a positive just to be sure. If you get a negative then you are definantly not pregnant

the bloodwork is the most effective so stick with that, but the best part is trying to make the baby so get off the pc and get busy.

It could have been a faulty test. Your doctors blood work could unlikely be wrong also. If I was you I would take another pregnancy test.
