How long does the HCG shot stay in your system!?!?


Well, today I am 6 days past a 5 day transfer. My HCG shot was 2 weeks ago tomorrow. I couldn't stand it any longer so I POAS (EPT) today and it was positive!!! I'm scared to believe it. In the last 4 years I have POAS over 100 times, and I can't believe my eyes! My blood test isnt scheduled until Wednesday morning. Could this be a false positive? Please respond, I so want to be excited, but I'm scared the trigger could be causing a false positive....

I hate to say this, but it depends. The HCG trigger shot can be in different doses. My RE told me that the HCG trigger stays in your system for 10 days. If you are 14 DPO, you are testing your HCG levels, not the trigger shot. Nevertheless, stay calm, don't be TOO excited. Wait for the blood test results.

All the baby dust & best of luck!

I have used Pregnyl and Ovidrel ... both were out of my system by 6 days passed trigger. Mine never took more than that ... I would say it's pretty safe to say after 2 weeks it is out of your system and that is a TRUE BFP.

Congrats!!!

Pregnyl has a half-life of 23h, Novarel and Ovidrel are similar. So, basically every day since you took your trigger the levels of hCG are decreasing by 1/2.

If you took 10,000iu hcg, it would take about 10-12d to be <5 iu in your blood. If you took 20,000iu add a day or two. Sometimes faster or slower depending on your body's drug metabolism and body fat percentage.

So, if it's really been 2 weeks (as in 14d), and you're testing positive, I'd say you have every reason to be hopeful!

Thanks everyone!! I know, I'm dying to call my mom, but I am going to wait until Wednesday. At this point, i figure I've been waiting for 4 years, what is another 3 days, so I can be SURE.

Thank you again for responding!!

Hi! I know this post was quite a while ago...but I was wondering how metabolism and body fat percentage can alter how fast the hCG trigger leaves the body.

Thanks!

It decreases the metabolism, or increases the time the trigger leaves the body. Also, if over 30 BMI, many REs will recommend 20,000iu hcg triggers over 10,000iu hcg for more effective trigger. Obviously, this would also take longer to metabolize.

Thanks for responding Beau Geste! And CONGRATULATIONS on your pregnancy! I hope it's been a happy, healthy and easy one. How exciting.

Do you think 14 days past the trigger would be the longest the trigger could stay in my system? I do have a slow metabolism (hypothyroid) and I am fluffy (PCOS). I only had a 10,000 trigger.

I did have a m/c at the end of July and my hCG went down really quickly. But every cycle is different. I don't know what to think anymore.
