Subject: 12dpiui with beta of 33...too low? Repeat not scheduled til
16dpiui...please help! Doctor please if you can answer...
> Hi everyone,
> I'm a 24 y/o woman with pcos who has been anovulatory since ttc starting
> in sept 02. I did 2 rounds w/ gonal F (first cancelled due to
> overstimming). This past cycle was my 1st ovulatory cycle since
> starting ttc. I'm using crinone in the 2ww.
>
> My bbts went triphasic at 11-12dpiui. I did a hpt (First Resp Early
> Result) and got a faint + at 12dpiui. Went for a beta yesterday (RE
> usually won't do til 14dpo but they said come in because of the +hpt)
> and the level was only 33.
>
> The nurse practitioner said this was + and indicative of very early
> pg'cy. I told her I was only 12dpiui and she said they usuallly don't
> test that early (she's the one who suggested I come in however). My
> repeat beta isn't until 16dpiui because my RE won't do betas on
> weekends.
>
> I've seen average 12dpo betas listed at 50 and 14dpo at 100. A few
> sites said 50 is normal at 14dpo. These sites also say the range can be
> quite large, from 17-100+ at 12dpo. However, I've come across very few
> women with such low initial beta numbers. I also think some who had
> very low initial #s probably just miscalculated ovulation, whereas I had
> a trigger and can be pretty sure I'm 12dpo.
>
> DH and I are refraining from celebrating as it doesn't look good from my
> perspective. I know all I can do is wait til the repeat.

> Could late implantation (would this correlate w/ temps going triphasic?)
