Question 1

is it possible for hcg to be detected in your blood  5 days after sex?

Accepted Answer

Possible: If there was pregnancy immediately, there is the possibility that B-HCG could be detectable.   If concerned though, save your money, be patient, and wait to see if the period is missed, then check the Preg test.  Good luck.

Question 2

is an hcg blood test accurate about 12 days after sex? thanks

Accepted Answer

May be too soon: Conception, as defined by the generation of a fertilized ovum, occurs within day or so of the sex. However, it takes about two weeks for the embryo to make enough HCG to produce a positive pregnancy test. Blood test may be done a day after a missed period. Home pregnancy tests should be done 4-5 days after the missed period. Use first morning urine and follow instructions for the test carefully.

Question 3

is a negative hcg blood test accurate if it been 4 weeks after sex?

Accepted Answer

: Yes , 4 weeks is sufficient. good luck

Question 4

could a blood test for hcg ever be wrong if i took it one month after sex?

Accepted Answer

Life is not perfect: And life is not exact.  If a test says pregnant, and there are no symptoms of pregnancy, just recheck another test.  If a test says not pregnant, but there are plenty of pregnancy symptoms, just recheck another test.  However, the blood test at one month after sex (with no sex since that event) is almost always correct.

Question 5

is a blood test 24 das after sex b hcg 0.1 accurate 24 days after sex accurate regardless of period?

Accepted Answer

HCG test: If you are certain about dates, a negative serum HCG test 24 days after sexual contact is accurate to be assured that the sexual encounter 24 days ago did not result in pregnancy.  Even if a period is delayed, ovulation occurs fourteen days before a period, so the "24 day" date is unlikely for pregnancy origin.

Question 6

how accurate is a beta hcg blood test 13 days after sex? can't go by period, got on depo after encounter. after how many days is blood test 100%

Accepted Answer

Call your doctor: Did you tell your doctor you had unprotected sex prior to getting the Depo?  Try not to be your own worst enemy.  If you had unprotected sex use Plan B or tell your doctor.  An IUD  could have prevented pregnancy as well.  Remember you still need protection from HIV, Herpes, HPV, Chlamydia, Gonorrhea, Syphyllis and other STDs and should use condoms.  Please protect yourself and avoid stress.

Question 7

i have an irregular cycle. how many days after sex can i take an hcg blood test for accuracy? my level was 'less than 1.2' 13 days after intercourse

Accepted Answer

About two weeks: You can take a pregnancy test about two weeks after to determine if you are pregnant.

Question 8

i have pcos last period over 6mos took a blood hcg test 22 days after sex how accurate?

Accepted Answer

Accurate: If you have not had a period for 6 months and you have pcos, then the problem is that you are not ovulating.  A test at 22 days after intercourse should accurately reflect if you are pregnant or not.  If the test is negative, then talk with your doctor about ways to induce ovulation as well as metformin.

Question 9

took emergency contraception (2hrs after sex), 19 days (2days missed period) later had negative quanti. hcg blood test. period still doesn't come.why?

Accepted Answer

Many reasons: While it is unlikely you are pregnant, that may still be an issue, so pay attention to how you feel as emergency contraception will not work with an ectopic pregnancy the same way. Many things can alter periods, including stress, exercise, medications, and even age. If your period has usual been very regular, this last cause is unlikely. Also, in the future please use regular contraception.

Question 10

i had sex 7 weeks ago. i had my period since then twice, first in time, second 4 days late. i had multiple negative urine tests. i had a blood test last week that said hcg less than 1. also, a negative ultrasound. am i still at risk of an ectopic pr?

Accepted Answer

No so far.: You had many tests done and it was negative. You can have further test done to make sure such as hysterosalpyngogram.
