Normal Progesterone Levels

Progesterone levels during pregnancy. What are normal progesterone levels? What does progesterone do?

The progesterone blood level in a normal pregnancy can be up to 10 times higher than when you are not pregnant.

  1. Progesterone levels are low before ovulation
  2. Progesterone levels rise within 7-10 days after ovulation
  3. Before you ovulate, progesterone levels are usually below 10 ng/ml
  4. In the middle of the second half of the cycle, midcycle, about 7-10 days after ovulation,  progesterone levels ate usually above 8-10 ng/ml.
  5. Progesterone levels are usually higher when you are pregnant, but cannot be used to test for pregnancy.  
  6. Even in a non-pregnant patient they can reach 20 ng/ml. 
  7. After ovulation, progesterone levels should be greater than 10 to 12 ng/ml to have a better chance of a good pregnancy outcome.
  8. Progesterone levels drop when you are not pregnant
  9. The progesterone drop induces the menstrual period
  10. Progesterone levels fluctuate a lot, even on the same day and from one top the other hour
  11. The hCG pregnancy hormone blood level is a better indicator of a viable pregnancy than the progesterone level.
  12. After 6 weeks of pregnancy the best indication that the fetus is doing well is to check the fetal heartbeat.
  13. Checking the progesterone level can be confusing because it's difficult to assess whether a low progesterone level means the pregnancy is already abnormal to begin with, or if the low progesterone is the cause of the bad outcome. Many doctors feel it's a failing pregnancy that triggers a low progesterone and that giving progesterone will not make a difference.
  14. Progesterone supplementation should be reserved to the following women: IVF, those with Injectable ovulation medications, those who have been shown to have immune reasons for miscarriages

THIS IS REALLY CONFUSED! I had miscarriage on April 1st,08 & did D&C thesame day. I was having nausea, sick, and dizzy last week. So I went to the hospital and result came back positive, serum Preg*Pos(dja) hcg, beta subunit, Qnt, serum-26. When I did home pregnancy test it showed Negative twince. I'm currently on FERTILAID for women & the tea. Though I asked my OB-Gyn if it possible to be pregnant so soon but he told me there is no way. What is going on here? Can I stop taking it or what? PLEASE I NEED YOUR HELP!

You can still have a positive pregnancy test after a miscarriage for a little while because the hormone is still present in your system.
