HCG Levels

Hello my beauties 😘 
Just wondering whether anyone else has had to have bloods to confirm pregnancy? I had my first bloods done on Wednesday & then again this morning as should rise... But found that my HCG was only at 298 at 4wk 6days (according to LMP) awaiting a call back from the hospital to see if it's risen or not. If not its not a healthy pregnancy 😔 But pregnancy tests are getting darker... Anyone else had low HCG levels & their baby is fine?Â
