Possibility Of Miscarriage Due To Levels Of Progesterone

User Profile
Hello Everyone This Is My First Time Posting So Please Be Patient With Me. I'm 7 weeks Pregnant And My Dr Is Concerned With The Possibility Of A Miscarriage Due To My Low Levels Of Progesterone. 1 Week Ago My Progesterone Level Was At 11 And Today I Was Told It Dropped Down To 5. My HCG Levels Are Also A Cause For Concern, They Started At 500 And Went Up To Mid 800 (don't remember the exact #) My Dr Told Me That They Are Rising But Not Doubling Like They Should. Today My HCG Was Well Over 1000 (2 days after 800 results) Still Rising But Not Doubling. I Have No Pain Or Bleeding & My Dr Has Ruled Out An Ectopic (I've Had One In The Past & My Left Tube Was Removed) I Have Had 3 u/s, The First One Showed Nothing (not even the sac) Second One Was Done A Week Later & Only Showed A Sac, Today Had The Third u/s And Once Again Only The Sac. My Dr Prescribed The Progesterone Vaginal Suppositories & I Have A Follow Up In A Week For A Repeat u/s And Blood Work To Make Sure Progesterone levels Are Rising. My Dr Has Told Me That There Is A Great Possibility That I Will Miscarry & I'm So Scared, Stressed & Just Going Insane With The Anticipation. Has Anyone Gone Through Something Like This? Any Help Will Be Greatly Appreciated. Thank You All For Your Time

Complications during Pregnancy Answer A19638

Welcome to the ehealthforum and I am really glad to help you out. HCG can first be detected by a blood test about 11 days after conception and about 12 - 14 days after conception by a urine test. In general the hCG levels will double every 72 hours. The level will reach its peak in the first 8 - 11 weeks of pregnancy and then will decline and level off for the remainder of the pregnancy.

But the hCG levels should not be used to date a pregnancy since these numbers can vary so widely. The results from an ultrasound after 5 - 6 weeks gestation are much more accurate than using hCG numbers.

Since you are having a history of ectopic pregnancy,routine checking of hCG levels is required.Low HCG levels may indicate possible miscarriage or an ectopic pregnancy.But low HCG levels are not the only indicator for a possible miscarriage. A perfectly healthy pregnancy may have low hCG levels also.

I suggest you not to take any stress and get a repeat ultrasound done which will rule out any miscarriage or ectopic pregnancy.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
