Can a blood test from your gyn tell your if your pregnant before a at home test?

Not really.: Far away and many years ago urine from a woman who might be pregnant was given to a rabbit. The rabbit was sacrificed, her ovarys were examined and if the rabbit had ovulated the woman was pregnant. Now rabbits are safe. We now use antibodies to hcg. The same test is done by you and the doctor. ...Read more

I had hCG blood test and it was a negative after 1 month of sex... How valid are blood tests? Can they ever tell me that i'm not pregnant when i'm not

Time & technique: Both urine and blood tests for HCG are very accurate in measuring hcg. It is better to do either test 4-5 days after a missed period. Negative pregnancy test done after one month of the last episode of sex is a good indication that the person is not pregnant. You should repeat the test 7-10 days later for an added measure. ...Read more

Dropping hcg: If your hcg is really dropping then you don't have a viable pregnancy. It should go up by at least 15% every 3-4 days. However, in case it was a lab error, I would repeat the hcg a few days after that 26 to confirm it did indeed drop. this sounds like a miscarriage. ...Read more

Preg tests say I'm pregnant but having regular period. Will blood test tell me for sure or read a miscarriage? When can I know for sure?

Preg tests say I'm pregnant but having regular period. Will blood test tell me for sure or read a miscarriage? When can I know for sure?

One can wait a week: Because a woman cannot have her normal regular period and also be pregnant at the same time, either she is not pregnant or the bleeding is not her regular period. The simplest way to figure this out is to repeat a home pregnancy test after 1 or 2 weeks. There is usually no urgency, but if one must know sooner, one can get 2 blood tests a few days apart to see if her HCG level is rising or falling. ...Read more

How to find out if your pregnant? My girlfriend feels pregnant and her belly is getting bigger but the urine and blood test come back negative. We have been trying for a baby for 2 months now and can't tell what's going on?

How to find out if your pregnant? My girlfriend feels pregnant and her belly is getting bigger but the urine and blood test come back negative. We have been trying for a baby for 2 months now and can't tell what's going on?

It : It is prudent to involve your doctor in your journey to get pregnant. Your doctor can recommend prenatal care and supplements as well as assistance in predicting a woman's most fertile times of the month to help increase your chances of conceiving. In the meantime, if your girlfriend has had a negative urine and blood test for the pregnancy hormone, then the pregnancy hormone was not detected. The pregnancy hormone can be detected in the urine 14 days after conception. If your girlfriend is pregnant, she will experience a missed period. Again, get your doctor involved in this journey to ensure your girlfriend's body is ready for this journey with the proper prenatal care. ...Read more
