HCG @ 5 weeks

Last night I ended up in the ER due to an ovarian cyst that burst and they ended up taking my blood and doing an ultrasound. I’m exactly 5 weeks yesterday. The ultrasound showed just a sac, which I assumed is all we would see. However, the HCG was around 2000 and the physicians assistant told me that is low for 5 weeks and it should be more around 10,000. I’m curious, what was your level at 5 weeks. I’m trying not to worry, but we lost our son at 35 weeks and every little thing worries me this time around.
