Karin...before you have a heart attack about trips. lol

Betas are all over the place for what is normal. My real life friend (IVF) got her first beta at 17dpo and it was 946...her second beta at 25dpo was 27,820. Normal for multiples was around 10,000 at that point. She had just 1 little bean in there.
Another friend from this board who Rio and I cycled with started with a beta of 13 and it went up very slowly...was pregnant with twins.
My same real life friend who had the extremely high betas...did an FET last June and her first beta at 17dpo was only 200 and something this time...she was freaking that it was too low compared to her 946 with her first pregnancy...and guess what? She has identical twins coming this time!!!
Another friend of a friend on my mommies board had huge huge betas (not IVF)...something like 10,000 for her first beta (not sure of dpo, but it was early) and she had just 1 bean in there, too.
However, like I said in an earlier post...another real life friend of mine had IUI and 2 took but one split...so she has 3 babies...a set of identicals and 1 fraternal...all boys. Yes, it can happen, but it is pretty rare. So try not to focus too much on the number.
Heck, at 17dpo for 2 of my pregnancies (Zach and a FET miscarriage) I had a beta of 524 (yep same exact number both times)...weird huh?
Point is...dont go having any heart attacks yet about trips...I have seen crazy numbers on here and in real life...and although your numbers are super high...I no longer put alot of stock in them. If you do have 3 coming by some crazy chance...you'll do just fine...my friend with the triplett boys...has a terrific time with 3 babies...and the pics she posts are to die for. lol She learned real quick on how to put them all on the same schedule...and she still has lots of me time too. The boys became each other's playmates so to speak.
