Beta at 16dpER is 73. That's a doubling time of 54 hours or so.
Still a bit low, but at least it's rising.
BetaBase says the average for 16dpo is 200, but I've found other sources on line that say that the average is closer to 100. Whatever.
There is also this study, that used to be encouraging to me.... http://www.squidoo.com/16dpo
Whatever. We'll see...Taken from Table 2
Summary of Outcome by hCG levels
What this study found:
25 - 50 hCG at 16dpo -- Four women in this study had hCG levels below 50 at this stage. The researchers concluded that with these levels less than 25% would continue on with their pregnancy with more than 75% miscarrying.
50 - 100 hCG at 16dpo -- Of 16 women, 25% continued on with their pregnancies.
100 - 199 hCG at 16dpo -- Of 27 women with these levels, 73% continued on with their pregnancies.
200 - 299 hCG at 16dpo -- Of 48 women, 96% continued on with their pregnancies
Over 300 hCG -- All 105 women continued on with their pregnancies.
RE wants me to come back on Wed or Thurs for another check. I just might go Tuesday instead!
