I had pretty low betas.
9dp5dt: 64
14dp5dt: 91
16dp5t: 200
18dp5dt: 500
My first ultrasound revealed two sacs. One was very tiny and the other was on track so based on that, we lost the twin between the first and second betas AND my first beta was the result of twins. If only one had implanted initially there is a good chance my first beta would have been less than yours. My points being, low betas dont have to mean anything bad, they have to start somewhere! Good luck!
