It varies woman to woman. I was 47 at 12 days past ovulation and the levels are suppoed to roughly double every two days. Hope that helps
From 7 days past ovulation until like 26 days past ovulation anything is possible!(this is home pregnancy test) Blood test (quantitive HCG) is more accurate after 7-10 days past ovulation(possible conception) All the best!
HCG levels begin building around 8 days past ovulation. For accurate results, it is best to wait until the day after you have missed your period.
Serum HCG levels are detctable at low levels as early as 7-9 days after ovulation.
== == == == It's possible that you could get these levels at 10 days past ovulation, though many women will need a little longer to develop this much HCG in their bloodstream. One measurement at this low level really doesn't tell you very much, a second test to see if it is rising is needed.
You can get pregnant agin. It is best to wait until your hcg is 0 before trying to get pregnant again.
HCG levels are detectable at low levels as early as 7-9 days after ovulation. During the first 3-4 weeks after fertilization the HCG level doubles every two days. By the fist missed period the level will be 50-250 mIU/ml. HCG will peak at approx. 60-70 days after fertilization at 80,000-150,000 mIU/ml, then gradually decrease during the remainder of the pregnancy.
A pregnant woman's hCG level's double every two days.
== == Some early home pregnancy tests can show a positive result as early as 10 days past ovulation and can detect levels of hCG (the hormone that shows pregnancy) as low as 20 mIU. I would guess that a blood test might show as early as 8. For most women, implantation occurs between 6-10 days past ovulation, and hCG will not be in your bloodstream until after implantation has occurred. The hormone level doubles every 36 hours or so, so even if the embryo implanted at day 6, a day or two would need to pass in order for the hormone to be present.
Have they checked for ectopic pregnancy?
With advances in technology it is now possible to detect pregnancy from the convenience of your own home before you have even missed your period. How early you can test depends on the type of test you are using.When should I test?Newer home pregnancy tests detect very small amounts of hCG, some as low as 5 mIU/L. With these very sensitive tests, it is possible to test positive as early as seven days past ovulation. It is important to remember that implantation occurs anywhere from seven to ten days past ovulation and women produce varying amounts of hCG, eventually forming a pattern of doubling hCG amounts every two to three days. While it is possible to test positive as early as seven days past ovulation, there is also a good chance that implantation has not occurred yet or that you are not producing hCG at a high enough level to be detected by a home pregnancy test. For best results, it is still recommended to wait until a woman has missed her period or 14 days past ovulation. For those that just can't wait, the very earliest you should test is seven days past ovulation.For the source and more detailed information concerning this subject, click on the related links section (Just Mommies) indicated below.
Yes, having low hcg levels or no hcg levels while pregnant can be hereditary
They help stimulate ovulation.
