positive test but low hcg levels

braelyn26 · February 2012

Can someone please give me some piece of mind, the date of my last period was Jan. 1st. my cycle is always 28 days so on Jan 31st i took a HPT and it was a very faint positive. My ob-gyn said ok we will see you March 12th, well i went to my primary doc for bloodwork to be sure and on feb. 1st my level was only 23, i repeated it on feb. 5th and it was 122. they said congrats you are about 2 wks pregnant but in reality i should have been 5 right? my ob said oh don't worry we don't even do bloodwork but i am worried, and i don't have many symptoms except bloating and exhaustion. has anyone else had low levels and had everything turn out fine?

Well technically when you're "5 weeks pregnant," that really means you're only actually about 2-3 weeks pregnant because they count pregnancy from the first date of your last menstrual period. So they could have meant that it's been about 2 weeks from when you probably ovulated (which would mean you're "5 weeks pregnant" if calculating based on LMP but only "2-3 weeks pregnant" if calculating based on when you ovulated).

Does that make sense?

Your doubling time is about 39-40 hours, which is great (usually they like to see it double every about every 48 hours).

As for how far along, you PCP may have meant you are approximately 2 weeks from conception (in most calculations you are "pregnant" for 2 weeks before you conceive). So 4 weeks pregnant would be 2 weeks past conception. Assuming you did have a perfect 28 day cycle with ovulation at day 14, you would have conceived around Jan. 15, so on Feb. 1 you would have been approximately 2 weeks past conception.

try not to worry Beta draws are usually only done if you have a history of losses or were undergoing IF treatments. be happy you are pregnant and as hard as this sounds to do be paitent and wait for your March 12 appt. And yes you are really 5 weeks pregnant sounds like GP was going from ovulation not LMP. GL

I see no reason to worry about those numbers. My first with DS was 14, a few days later it was 117. (I have no idea how I remember that, but can't remember what I had for lunch yesterday.) Relax and enjoy!

Honestly, this is why I skipped the hcg bloodwork with each pregnancy after DS's. They just cause a bunch of worry, imo, and they don't mean anything in the long run.

I got tripped up on this too when I was pregnant with my first. With DS, they called with my first beta and said you're 1-2 weeks pregnant. I remember I was at work and got off the phone crying because I knew I was about four weeks and I thought that meant something was wrong with the baby. I called one of my BFFs in tears, who explained to me what they probably really meant was 1-2 weeks gestation. She was right.

If the doctor was concerned about your levels, he/she would've said so.
