Slowing beta hcg numbers. Should I be concerned?

14 dpo 142
16 dpo 396
18 dpo 874

I know that the numbers don't look obviously bad, but what I'm concerned about is the dramatically slowing doubling rate. From 14 to 16, it's a 32 hr doubling rate, then from 16 to 18, it slowed to 42 hours. That seems like big slowdown to me. I know it technically meets the needing to double in 48 hours rule, but something just seems off about it. I've had a few miscarriages where the betas started off really low and were very slow to double, so I tend to watch this data very closely and fret about it.

Any thoughts? Would you ladies have expected a higher day 18 number and for the rate to keep up?
