Well, my 4th and final beta was today - a 75% increase over 2 days ago (from 1567 to 2736). My nurse once again reassured me that this is perfectly normal, not doubling after 2 days (guess I am closer to every 3 days, which I read is fine), and that the RE isn't concerned. If the RE isn't concerned, then I won't be! She also said that my estrogen levels are "super" and told me to stop the estrogen supplement.
Below is the chart of all my betas. Looks like one little cashew (I like cashews more than peanuts). Don't know if my increases are off because my first beta was so high?
My first ultrasound is on Monday. Please, God, let this be a healthy pregnancy!
