Second beta

So, my first beta was technically 9dp3dt (fresh transfer) and was really low at 12. I went for my second one today, pretty much 48 hours later and it was 23.6.

I’m really worried that it will not continue to double. I had a result of 18 after my third IUI (14dpiui) and it doubled at first and then dropped. It ended up in a chemical.

Going for a third blood draw on Monday/Tuesday. I’m worried. Although, I’ve also been reading and it seems my first beta was pretty early.

What do you guys think? I’d really appreciate some opinions. Thanks.
