I had a blighted ovum in Dec of 2014, so we're monitoring this one more closely and I'm even more worried!

At 4 weeks 2 days, my level was 130.

Then at 5 weeks exactly, they were 1828. They more than doubled and that is fantastic. But I'm worried that they're low.

Seems too low to me. I'm scared of another miscarriage.

I'm also having pain, lower back... left side... and pelvic region, left side. I have a history of kidney stones, so I'm hoping that's all it is and not an ectopic pregnancy. I'm waiting on a call back from my ob regarding the pain. I just wish they'd do a transvaginal u/s to show that at least the sac is in the right spot.

Any insight to, in my opinion, low but doubling every 31 hrs hcg? Pain? Anything?

Please help this worried mama. I just want my rainbow baby to be healthy and happy!

Thank you in advance.
