Hope it is OK if I post. I know how hard it is. I had alot of negativity (not on this board, but elsewhere) on my low beta (starting at 21 10dp5dt). It turned out OK. I am still in first tri- not out of the woods yet- but if something happens, it isn't because of my low initial betas.
I did alot of googling (more than was healthy) and found success stories starting even in the single digits. Unfortunately, it is just a waiting game and for me, they did serial betas (every couple days).
I am thinking very positive thoughts for you!
