Do I need to get an HCG pregnancy blood test at the same time every time I take it be accurate?

The tests are very accurate. They are manufactured with certain controls built in, but you should follow all the instructions that you were given by teh clinic or whom ever will be drawing the blood.

A prenancy test should be accurate approximately 12 days after you had sex.  A full period is very uncommon to have when you are pregnant.  Slight spotting is more common and can be called "implantation bleeding".  Think about when you had sex and add 12 days, take a test and it should be accurate.  Hope that helps.

The answer to your question is: Yes.  The Home Pregnancy test works by detecting HCG in your urine.  Only when you're pregnant is HCG present in the urine.  You can be pregnant and not have enough to turn one positive.  You can go to your doctor and ask for a Beta Quantitative Analysis. It will tell you if you're pregnant and approximately how far along you are.

HCG is the hormone that is detected in pregnancy tests, both blood and urine so any pregnancy test will not be accurate.

A blood test can usually detect early pregnancies.

When you go to your Dr. he will probably do a blood test that will verify whether you are pregnant or not.  He will have options that you can decide on.  Trust in him and in yourself.  Just keep an open mind.

A standard pregnancy test detects the amount of a hormone called HCG (human chorionic gonadotropin), which is present in greatly elevated levels in the urine (or blood) during early pregnancy. This elevated level may not be high enough to be detected in a given sample, and it increases over the first weeks of a pregnancy so if it's not positive the first time, it may be a few days later.

no. the pregnancy test works by detecting hormones in the body that are only there when a woman is pregnant. a false positive is won't happen, a false negative can happen, though.

Yes, it is possible to be pregnant and have a negative home pregnancy test.  The test works by detecting HCG in your urine that you produce when you are pregnant.  You CAN be pregnant and not have enough HCG to turn one positive.  If you really want to know, go to your doctor and ask for a Beta Quantitative Analysis, which is the definitive blood test for pregnancy.

No it's not. Your body won't be producing enough HCG to trigger a positive. A blood test MAY pick it up...but it probably won't be high enough to officially declare it a pregnancy

Anything is possible, but if the proper testing and blood work was done, it is highly unlikely. The body makes and releases certain hormones at specific times during a woman's cycle and when pregnancy is achieved, there are even more hormones that surge into the system. If they don't reach specific levels at the right time, it is highly unlikey that the body would be able to maintain the pregnancy. This would show up in blood work. Also, once those hormaones are present it takes a few months for them to return to pre-pregnancy levels, so you may still feel strange. An internal sonogram is another way they can check and is pretty specific. It is done by placing the sonogram probe at the vaginal opening and the uterus and ovaries are very visible. I saw my babies each week as they developed from the week of conception. I miscarried my first at seven weeks and it was only the size of a grain of rice. I have a picture of it from the six week exam and it is little bigger than a spot. I had to wait a few months before trying again to allow the hormones to come down, but with the next try I got my wonderful son. If you have misgivings about your doctor's diagnosis, you should see another doctor to ease your mind. Best wishes to you.

Normally, once you take a pregnancy test, it is recommended that you report to your doctor to confirm the results. Although OTC pregnancy test are "kinda" accurate, the only way to truly determine pregnancy, is via laboratory test known as Ascheim-Zondek (A-Z test). (see also pregnancy tests that check urine and those that test blood)\n\nNevertheless, the benefit of birth control pill is not only 99.8% effective in preventing pregnancy, but they also help to make shorter, lighter periods, along with regulating periods. This accounts for the brown discharge and lighter periods - with some up-to-date hormonal birth control, periods only come once every three (3) months.\n\nSo I don't believe you should have to worry about a misscarriage from the meds you were prescribed from your wisdom tooth, including the antibiotics. There has never been a report of becomming pregnant when "the pill" is used correctly.\n\nAlthough you did not confirm the results of the pregnancy test with your doctor, you can count on the results of the five (5) OTC pregnancy tests to be accurate.  Within 2-3 months, you  body should adjust to the pill, your period should become normal, but if not, consult with your doctor.\n\nHope this answers your question!

You have been asking the same question for 2 months now ... in the time it takes you to type this you could have purchased 100 pregnancy tests. Is the real problem that you have a need for attention because the pregnancy question is getting old. If you really think you're pregnant, try taking the advice you've been given over and over and over again. GO TAKE A TEST!

Yes- this is very normal.  What I would do though is to see your doctor for a blood pregnancy test, to confirm that you are indeed pregnant.

They are reasonably accurate but even a positive result needs to be checked by the doctor. See your doctor for a blood test to check everything out. Those symptoms can also be related to stress, espeially if you think you're pregnant!
