I am going to ignore all of the ridiculous crap in this thread 
, and answer you seriously.
I did betas with my first pregnancy, and it's the only reason we knew something was wrong. Betas didn't rise well, but we had a heartbeat for a week. RE prepared me for the worst despite the heart beat, and thank God that he did because we lost the baby.
I swore I wouldn't go through beta hell again, but in order to be followed by my RE and get an early u/s, I had to, since they won't try the u/s until levels are 1,000+. It was AWFUL, but I got through it because I wanted that ultrasound. But if I had had my choice, I would never have done it.
It's a catch-22. The rising betas were very reassuring with this pregnancy, but the waiting for the results was horrendous. I went into the chapel at my work to make every call. I truly do not blame you for skipping betas.
