A beta pregnancy test is a blood test administered to determine the levels of the HCG hormone in a woman's body. Technically you are pregnant if your number is above 5 on your first beta, which is typically scheduled for 14dpo or 14 days past ovulation (the day of egg transfer with IVF) but it is my understanding that most clinics like to see a higher number by then. However, the most important indication of how well things are progressing is with the second beta, which they will normally do 2-3 days after the first. Your numbers should be consistently rising at the beginning of your pregnancy, not staying the same or dropping.
It's too hard to tell if you are having multiples just by your beta numbers. Even though there is often a correlation between high beta numbers and multiples, it is not always the case. I have read where women with fairly low numbers ended up being pregnant with triplets and I've heard about people with high numbers having singletons, so you never really know.

This past Friday my first beta was 333 and three days later it had, thankfully, risen to 1025. Next week is the real deal, however, when I get my first pregnancy ultrasound and hopefully we will see some real evidence of my little emby (or embies?) in the form of a gestational sac or two. :)
It's true, even when you finally get pregnant, the worrying doesn't stop, it just changes to a different kind of worry. And I imagine when the baby is born, a whole new set of worries begins. So I am committed to thinking positively and taking the very best care of my little guy or guys and staying strong and enjoying each moment. I worked very hard for this and I am going to make the most of it!

(yay for me!!)
