Thanks for all the lovely and supportive comments.
I must admit that Gwinne's comments threw me into another bout of anxiety. And so now I'm second guessing my decision. And I'm leaning towards going for an ultrasound later this week to look for a gestational sack (I'm 5w2d right now, but with low betas, I think it's still quite possible that nothing is visible yet.)
What's hard with low betas is that the absence of a sack right now MIGHT be meaningful... or it might not.
(Please, please, don't offer anything other than encouragement right now. My fragile psyche can't handle any more scary ideas.)
What I really wish, I guess, is that I could figure out a way to just chill the f*ck out, regardless. I thought I had that covered when I got my beta results on Friday. I was just reveling in that number. But here I am, back in the mosh pit of anxiety. All over again.
And truthfully... will I feel better after I see a heartbeat? Or will I start to freak out again a couple of days later? I don't think I will, but... welcome to the 35ww, indeed!
