HCG levels rising, but not quickly....thoughts?

Hi lovely ladies...
I normally post in the LTTC pregnancy thread, but wanted to get advice from as many people as possible, so thought I'd pay a visit here too. I am nervous, after suffering an ectopic pregnancy and going through IVF and have been having HCG levels monitored.
They started going up at the right rate, but yesterday's BT showed that they've gone up, but more slowly than they should have. My IVF nurse said not to worry yet, as all could still be fine, and sometimes women do have slower patches and then all returns to normal. She said if it's still slow next week then we will be a bit concerned.

Has anyone else had slow rising levels at any time, and then found all was OK?

my levels are
16DPO 360
23DPO 3600
31DPO 8600

Thanks for any feedback.... :)

I have a scan booked for Oct 14..am going to try and have one next week instead.

:D Those are great levels.

Here is a link showing the ranges your levels should be in. I had a m/c where my levels were rising more slowly than they ought and they never got that high (and I was 8 weeks) nor were they going up at that rate. I wouldn't be worried about those levels if they were mine.:D Nice work!
Congrats on your new pregnancy!

Thanks for your reassurance Gabi... I think the main worry my nurse had was that the rate the levels were rising was quite a bit slower this week...but yes, I am encouraged the levels are high and within the right range.
I am actually now going for a scan tomorrow! Nervous and excited. I :pray: everything is OK this time. I don't want any depressing scans this time. But I do feel much different so here's hoping!
