Help!!

Nessa

Hi ladies I have a couple questions first of all I had my blood drawn at the Er last night cause I was sick and dizzy so I went in they said my hcg level was only 374 I was 4 weeks 6 days and they did an ultrasound and seen nothing but thickened endometrium lining I’m a little worried does this mean the baby may not develop!! I’m so worried cause I’ve had miscarriages in the past and with my two boys I was high risk with them and I have not had any bleeding or anything just light cramping but that was a week ago
