I'll skip to the chase, because I am really freaking tired, like, all the time now. It's basically my only pregnancy symptom so far, other than some digestive issues that I will spare you.
Beta #2 was 382. That's a doubling time of 42 hours, which is good good good. For my non-infertile peeps, in 85% of pregnancies, the level of hCG (human chorionic gonadatropin, the pregnancy hormone which is secreted by the rudimentary placenta) doubles every 48 to 72 hours in the first couple of weeks of pregnancy. So, a 42 hour doubling time is fine and good, and I am relieved.
I don't think most clinics do this, but mine makes me keep coming in for betas until I reach 1000. So, I go back on Friday, and probably one more time after that. Back in May, my third beta had a slower doubling time (56 hours), which was within normal parameters, but in retrospect I wonder if the slowing was a warning sign. Beta 4 last time was an abysmal 96 hour doubling time, and caused my RE to freak out and think I might have an ectopic pregnancy. So obviously I am anxious about the next couple of betas. On the one hand, I'd love to be done with the beta coaster, but on the other, I guess more data points between now and ultrasound is not such a bad thing.
It's still very early. Fingers crossed.
