I know it's hard. I've been there many, many times. And there is, unfortunately, no answer to your question. Beta numbers vary so much from woman to woman and pregnancy to pregnancy. The only REAL way to know for sure is to go for the blood test after enough time has passed. But I would say that by testing before 12 dpo you're setting yourself up for disappointment no matter if you're pregnant or not, since most women wouldn't get a bfp that early. For me, it had to be more than 15 dpo.
Hoping for you that you ARE pregnant and that you find a way to make this week go by a little faster.
