Trying to Get Pregnant

Positive Pregnancy Test, Inconclusive Blood Test

Hi, my bf and I have been trying to conceive for awhile now. On March 12, I took a Clear Blue digital test and it came back positive. I took a few more tests of different brands (ClinicalGuard test strips from Amazon and First Response) and those all came back positive as well. 

On March 17th I went for a blood test. It came back inconclusive with only 10 mIU/mL found in my blood. 

I took a few more pregnancy tests and they came back negative or very very faint positive. 


I am scheduling an appt with my OBGYN, but I still am curious if anyone has any idea as to  what could have caused this because I thought it takes weeks for HCG to leave your body? Could it really go down from 25 mIU/mL + (standard level for most pregnancy tests to show a positive) to a 10 mIU/mL in just 5 days? 


Thank you in advance for your help!

  • Okay. Wow, some of you people are so rude! I genuinely just wanted to know if anyone had a similar experience and what happened to them. I’ve never been pregnant before so I obviously don’t know what to expect. Shame on you.

    @kayleenicolerichie Like @holly321 said, it sounds like you had a chemical pregnancy. 10 miU/mL is still considered pregnant (5 or under is considered normal), but if your levels are decreasing that's indicative of a loss. It usually does not take hCG very long to leave your system when you're that early into a pregnancy. If you have other questions, you may want to introduce yourself over at the TTCAL board in the child loss section. 

    ETA: I'm also sorry for your loss.

  • @kayleenicolerichie a lot of woman here haven’t been pregnant before.  And honestly no one knows what YOU should expect with YOUR body.  

    Tw Tw I have been pregnant many times and dealt with several losses, all of which have been completely different than the one before.  My most recent was a chemical pregnancy, I had positive tests on Friday, blood work drawn on a monday and started bleeding on Wednesday.  My Monday level was a 7.  
    But the time before that, my HCG was 16,000 a week after my d&c, dropped for about a month then I traumatically delivered a mass tumor out of the blue on the way to work and my levels rose.  No one saw that one coming.

    I believe the half life of hcg is something like 2 days...so if its 10,000, 2 days ish later it should be 5000, etc... it does go quickly, also know this from experience.
