Oh good you think so!?
My next blood will be taken at around 10am Sunday morning, so approx 68 hours later, I'm guessing they'll want to see a minimum of 7500 ish?
You might be surprised how much it will go up, mine went from 6400 to 23000 in 4 days. Though not everyone is the same. Also seeing your levels at 3300 makes me think they jumped the gun on the ultrasound. Though they can give you piece of mind they also can cause stress when you don't see what you expect.
Good luck hopefully your results come back nice and high.
