Hi Ladies,

Have finally graduated from long time stalker to first time poster!

I am 8 weeks today. I had vaginal U/S (ergh!) 5 days ago which showed HB 151 and good measurements. Had slight spotting of old blood 4 days ago (I think due to rough usage of dildo cam) which stopped almost immediately however GP ordered HCG tests to reassure me all is fine. First HCG showed 72,800 and 2.5 days later had only risen to 80,300. Everything I am googling is telling me they should have doubled? Am I about to m/c?

Desperately want everything to be ok!

I think it only doubles for the first few weeks (ie around 3 weeks to 6 or 7 weeks). Am pretty sure that after a certain point it slows right down and eventually plateaus at around 8 or 9 weeks. A scan with a healthy heartbeat is a MUCH MUCH better indicator of a likely continuing pregnancy than hCG at this stage.

Good luck original.gif

my understanding is that your HCG levels peak between 8 and 10 weeks and then they start to drop again. So I would think that around that time they're not going to be doubling every 2 days like they would have been to start with.

I'm only 13wks preg with my first so I'm far from being an expert in this but that's my understanding.

Hi,

I don't think I am going to be much help, but my understanding was that your HCG levels stop doubling after the first 6 weeks or so.... then they just gradually increase.

Once your HCG levels reach approx. 6000 or there abouts it's normal for the rate of increase to slow dramatically. Checking for HCG double time is only effective when done in early pregnancy. Between 4 and 6 weeks or so is when it increases the most. 6+ weeks is when it tends to slow for most until double time is well over 100 hours.

Eventually it stops all together and will even go down a bit. It's really a waste of time to check for HCG at that stage in pregnancy unless you're looking to check for a decrease/pending miscarriage.
