My 1st beta was drawn at 14dpo and was 221. You will see a large flucuation in beta counts as every woman and every pregnancy is different. One beta number isn't really helpful as far as the progress/viability of the PG, you really need to have an every other day draw to be able to see your doubling time. The website below is also very helpful in comparing beta numbers...
