Hcg question

Found out Wednesday that we’re expecting! Went in for blood work since I have history of early MCs and the nurse told me my HCG was 744. When my chart finally updated online it shows something completely different.

Am I missing something? Is there a different scale that she converted it to maybe? Idk. The low number has me worried since I’m nearing 6 weeks.

Any opinions/experiences??

Update**

Got tested again to see if it rises(pending), can’t call in until tomorrow for those ones.
