High hcg levels

Daisy • Princess Arabella 👸👑

So i went to the drs at 8 wks ( Accor to last period) baby measured 5weks and 6 days , no heartbeat. Dr said not to worry it could be too early but now I’m concerned because i had blood work done prior to which i guess would’ve put me at 4 weeks , my hcg was 44000 and a week before that 435 . Should i be worried ?
