In my free time, I google things about beta results and, from most of the posts on the message boards, the general consensus is that beta numbers vary so much from person to person and pregnancy to pregnancy that you can't really tell anything from them related to multiples. However, there's this website call Beta Base (betabase.info), that has about 70,000 beta results from successful pregnancies broken down by how many babies (singleton, twins, triplets) and the day of the beta test (days past ovulation). Now, I'm a "numbers" gal, so once I figured out how this website worked, I thought it was the best thing ever!! Why waste time going from message board to message board to look up beta numbers, when I can waste time on a website that has already complied thousands of beta numbers! =P
After looking around on the website, I discovered a few things about my high beta numbers. Ok, so my second test was 13dp5dt, which is 18 days past ovulation (dpo). So first I went to the singleton pregnancies and on 18dpo, 4,085 women with singleton preg reported their beta results for that day. Out of those women, only 61 had a number of 2200+. Remember, my number was 2806. Those 61 women translates into 1.5%. So only 1.5% of the women who reported their betas on this website had a number as high as mine or higher and still had a singleton. 1.5%..... that's it!
So then I think to myself, okay let's look at the twin numbers. So at 18dpo, 1,970 women reported their betas for successful twin pregnancies. Only 113 women had a beta over 2500+. So that means that 5.7% of women with twin pregnancies had a beta as high as mine or higher. So even most of the women with twin pregnancies, had a much lower number than me on 18dpo!
Soooo then I look up triplet pregnancies! Out of 303 reported triplet pregnancies, 89 women had a beta of 2100+ on 18dpo. That means 29% of women had a beta as high as mine or higher. So my number is even on the high end of that scale! The other 71% had a lower number than me on 18dpo with a triplet pregnancy.
I know that there is no predicting the future... and I am being patient until the day of the ultrasound, but it's still fun to think about!! :)
